Add rate limiter for S3 API layer (#9196)
- total number of S3 API calls per server
- maximum wait duration for any S3 API call

This implementation is primarily meant for situations
where HDDs are not capable enough to handle the incoming
workload and there is no way to throttle the client.

This feature allows MinIO server to throttle itself
such that we do not overwhelm the HDDs.

fix: various optimizations, idiomatic changes (#9179)
- acquire since leader lock for all background operations
  - healing, crawling and applying lifecycle policies.

- simplify lifecyle to avoid network calls, which was a
  bug in implementation - we should hold a leader and
  do everything from there, we have access to entire
  name space.

- make listing, walking not interfere by slowing itself
  down like the crawler.

- effectively use global context everywhere to ensure
  proper shutdown, in cache, lifecycle, healing

- don't read `format.json` for prometheus metrics in
  StorageInfo() call.

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 822eb5ddc7 Bring in safe mode support (#8478)
This PR refactors object layer handling such
that upon failure in sub-system initialization
server reaches a stage of safe-mode operation
wherein only certain API operations are enabled
and available.

This allows for fixing many scenarios such as

 - incorrect configuration in vault, etcd,
   notification targets
 - missing files, incomplete config migrations
   unable to read encrypted content etc
 - any other issues related to notification,
   policies, lifecycle etc

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.

Harshavardhana 9e7a3e6adc Extend further validation of config values (#8469)
- This PR allows config KVS to be validated properly
  without being affected by ENV overrides, rejects
  invalid values during set operation

- Expands unit tests and refactors the error handling
  for notification targets, returns error instead of
  ignoring targets for invalid KVS

- Does all the prep-work for implementing safe-mode
  style operation for MinIO server, introduces a new
  global variable to toggle safe mode based operations

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.
