Fix an issue where MinIO was logging every error twice (#8953)
The logging subsystem was initialized under init() method in
both gateway-main.go and server-main.go which are part of
same package. This created two logging targets and hence
errors were logged twice. This PR moves the init() method
to common-main.go

Klaus Post c7178d2066 Profiling: Add base, fix memory profiling (#8850)
For 'snapshot' type profiles, record a 'before' profile that can be used 
as `go tool pprof -base=before ...` to compare before and after.

"Before" profiles are included in the zipped package.

[`runtime.MemProfileRate`](https://golang.org/pkg/runtime/#pkg-variables) 
should not be updated while the application is running, so we set it at startup.

Harshavardhana 0879a4f743 rest/storage: Remove racy LastError usage (#8817)
instead perform a liveness check call to
verify if server is online and print relevant
errors.

Also introduce a StorageErr string error type
instead of errors.New() deprecate usage of
VerifyFileError, DeleteFileError for gob,
change in datastructure also requires bump in
storage REST version to v13.

lock: improve locker initialization at init (#8776)
Use reference format to initialize lockers
during startup, also handle `nil` for NetLocker
in dsync and remove *errorLocker* implementation

Add further tuning parameters such as

 - DialTimeout is now 15 seconds from 30 seconds
 - KeepAliveTimeout is not 20 seconds, 5 seconds
   more than default 15 seconds
 - ResponseHeaderTimeout to 10 seconds
 - ExpectContinueTimeout is reduced to 3 seconds
 - DualStack is enabled by default remove setting
   it to `true`
 - Reduce IdleConnTimeout to 30 seconds from
   1 minute to avoid idleConn build up

Remove safe mode for invalid entries in config (#8650)
The approach is that now safe mode is only invoked when
we cannot read the config or under some catastrophic
situations, but not under situations when config entries
are invalid or unreachable. This allows for maximum
availability for MinIO and not fail on our users unlike
most of our historical releases.

Harshavardhana e9b2bf00ad Support MinIO to be deployed on more than 32 nodes (#8492)
This PR implements locking from a global entity into
a more localized set level entity, allowing for locks
to be held only on the resources which are writing
to a collection of disks rather than a global level.

In this process this PR also removes the top-level
limit of 32 nodes to an unlimited number of nodes. This
is a precursor change before bring in bucket expansion.

Harshavardhana 4e63e0e372 Return appropriate errors API versions changes across REST APIs (#8480)
This PR adds code to appropriately handle versioning issues
that come up quite constantly across our API changes. Currently
we were also routing our requests wrong which sort of made it
harder to write a consistent error handling code to appropriately
reject or honor requests.

This PR potentially fixes issues

 - old mc is used against new minio release which is incompatible
   returns an appropriate for client action.
 - any older servers talking to each other, report appropriate error
 - incompatible peer servers should report error and reject the calls
   with appropriate error

Harshavardhana d28bcb4f84 Migrate all backend at .minio.sys/config to encrypted backend (#8474)
- Supports migrating only when the credential ENVs are set,
  so any FS mode deployments which do not have ENVs set will
  continue to remain as is.
- Credential ENVs can be rotated using MINIO_ACCESS_KEY_OLD
  and MINIO_SECRET_KEY_OLD envs, in such scenarios it allowed
  to rotate the encrypted content to a new admin key.

Anis Elleuch a49d4a9cb2 xl: Rewrite auto-healing and implement auto new-disk healer (#8114)
The new auto healing model selects one node always responsible
for auto-healing the whole cluster, erasure set by erasure set.
If that node dies, another node will be elected as a leading
operator to perform healing.

This code also adds a goroutine which checks each 10 minutes
if there are any new unformatted disks and performs its healing
in that case, only the erasure set which has the new disk will
be healed.

Harshavardhana 36e12a6038 Assume local endpoints appropriately in k8s deployments (#8375)
On Kubernetes/Docker setups DNS resolves inappropriately
sometimes where there are situations same endpoints with
multiple disks come online indicating either one of them
is local and some of them are not local. This situation
can never happen and its only a possibility in orchestrated
deployments with dynamic DNS. Following code ensures that we
treat if one of the endpoint says its local for a given host
it is true for all endpoints for the same host. Following code
ensures that this assumption is true and it works in all
scenarios and it is safe to assume for a given host.

This PR also adds validation such that we do not crash the
server if there are bugs in the endpoints list in dsync
initialization.

Thanks to Daniel Valdivia <hola@danielvaldivia.com> for
reproducing this, this fix is needed as part of the
https://github.com/minio/m3 project.

This will allow the cache to consistently work for

- This PR changes the cache backend format, and all existing
content will be migrated to the new format. Until the data is
migrated completely, all content will be served from the backend.

This PR introduces two new features

- AWS STS compatible STS API named AssumeRoleWithClientGrants

```
POST /?Action=AssumeRoleWithClientGrants&Token=<jwt>
```

This API endpoint returns temporary access credentials, access
tokens signature types supported by this API

  - RSA keys
  - ECDSA keys

Fetches the required public key from the JWKS endpoints, provides
them as rsa or ecdsa public keys.

- External policy engine support, in this case OPA policy engine

- Credentials are stored on disks

This PR is the first set of changes to move the config
to the backend, the changes use the existing `config.json`
allows it to be migrated such that we can save it in on
backend disks.

In future releases, we will slowly migrate out of the
current architecture.

Anis Elleuch 9c5e971a58 Add new console/http loggers (#6066)
- Add console target logging, enabled by default.
- Add http target logging, which supports an endpoint
  with basic authentication (username/password are passed
  in the endpoint url itself)
- HTTP target logging is asynchronous and some logs can be
  dropped if channel buffer (10000) is full

Anis Elleuch be1700f595 Avoid startup abort when a notify target is down (#6126)
Minio server was preventing itself to start when any notification
target is down and not running. The PR changes the behavior by
avoiding startup abort in that case, so the user will still
be able to access Minio server using mc admin commands after
a restart or set config commands.

Andreas Auernhammer cd152f404a replace os.Exit with panic for logger.CriticalIf (#6065)
This commit prevents complete server failures caused by
`logger.CriticalIf` calls. Instead of calling `os.Exit(1)`
the function now executes a panic with a special value
indicating that a critical error happend. At the top HTTP
handler layer panics are recovered and if its a critical
error the client gets an InternalServerError status code.

Further this allows unit tests to cover critical-error code
paths.

Nitish Tiwari 6ce7265c8c Add support for CopyObject across regions and multiple Minio IPs
This PR adds CopyObject support for objects residing in buckets
in different Minio instances (where Minio instances are part of
a federated setup).

Also, added support for multiple Minio domain IPs. This is required
for distributed deployments, where one deployment may have multiple
nodes, each with a different public IP.

Nitish 6df1e4a529 Add functionality to add old buckets to etcd on startup
Buckets already present on a Minio server before it joins a
bucket federated deployment will now be added to etcd during
startup. In case of a bucket name collision, admin is informed
via Minio server console message.

Added configuration migration for configuration stored in etcd
backend.

Also, environment variables are updated and ListBucket path style
request is no longer forwarded.

- remove old bucket policy handling
- add new policy handling
- add new policy handling unit tests

This patch brings support to bucket policy to have more control not
limiting to anonymous.  Bucket owner controls to allow/deny any rest
API.

For example server side encryption can be controlled by allowing
PUT/GET objects with encryptions including bucket owner.
