heal: Add info about the next background healing round (#9122)
- avoid setting last heal activity when starting self-healing

This can be confusing to users thinking that the self healing
cycle was already performed.

Add goroutine profiles (#9078)
Allow downloading goroutine dump to help detect leaks
or overuse of goroutines.

Extensions are now type dependent.

Change `profiling` -> `profile` prefix, since that is what they are 
not the abstract concept.

fix and improve KMS server info (#8944)
This commit fixes typos in the displayed server info
w.r.t. the KMS and removes the update status.

For more information about why the update status
is removed see: PR #8943

refine the KMS admin API (#8943)
This commit removes the `Update` functionality
from the admin API. While this is technically
a breaking change I think this will not cause
any harm because:
 - The KMS admin API is not complete, yet.
   At the moment only the status can be fetched.
 - The `mc` integration hasn't been merged yet.
   So no `mc` client could have used this API
   in the past.

The `Update`/`Rewrap` status is not useful anymore.
It provided a way to migrate from one master key version
to another. However, KES does not support the concept of
key versions. Instead, key migration should be implemented
as migration from one master key to another.

Basically, the `Update` functionality has been implemented just
for Vault.

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 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 b52a3e523c Avoid using fastjson parser pool, move back to jsoniter (#8190)
It looks like from implementation point of view fastjson
parser pool doesn't behave the same way as expected
when dealing many `xl.json` from multiple disks.

The fastjson parser pool usage ends up returning incorrect
xl.json entries for checksums, with references pointing
to older entries. This led to the subtle bug where checksum
info is duplicated from a previous xl.json read of a different
file from different disk.

Andreas Auernhammer 810a44e951 KMS Admin-API: add route and handler for KMS key info (#7955)
This commit adds an admin API route and handler for
requesting status information about a KMS key.

Therefore, the client specifies the KMS key ID (when
empty / not set the server takes the currently configured
default key-ID) and the server tries to perform a dummy encryption,
re-wrap and decryption operation. If all three succeed we know that
the server can access the KMS and has permissions to generate, re-wrap
and decrypt data keys (policy is set correctly).

This PR adds two new admin APIs in Minio server and madmin package:
- GetConfigKeys(keys []string) ([]byte, error)
- SetConfigKeys(params map[string]string) (err error)

A key is a path in Minio configuration file, (e.g. notify.webhook.1)

The user will always send a string value when setting it in the config file,
the API will know how to convert the value to the appropriate type. The user
is also able to set a raw json.

Before setting a new config, Minio will validate all fields and try to connect
to notification targets if available.

Drain response body properly for http connection pool (#6415)
Currently Go http connection pool was not being properly
utilized leading to degrading performance as the number
of concurrent requests increased.

As recommended by Go implementation, we have to drain the
response body and close it.

Harshavardhana 0e02328c98 Migrate config.json from config-dir to backend (#6195)
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.

Harshavardhana 556a51120c Deprecate ListLocks and ClearLocks (#6233)
No locks are ever left in memory, we also
have a periodic interval of clearing stale locks
anyways. The lock instrumentation was not complete
and was seldom used.

Deprecate this for now and bring it back later if
it is really needed. This also in-turn seems to improve
performance slightly.

Admin API is not an S3 API and hence it is not required
to honor server region while validating admin API calls.

Andreas Auernhammer 9fb94e6aa8 ensure authenticated request bodies for Admin-API (#5984)
This commit adds a check to the server's admin-API such that it only
accepts Admin-API requests with authenticated bodies. Further this
commit updates the `madmin` package to always add the
`X-Amz-Content-Sha256` header.

This change improves the Admin-API security since the server does not
accept unauthenticated request bodies anymore.

After this commit `mc` must be updated to the new `madmin` api because
requests over TLS connections will fail.

Harshavardhana fb96779a8a Add large bucket support for erasure coded backend (#5160)
This PR implements an object layer which
combines input erasure sets of XL layers
into a unified namespace.

This object layer extends the existing
erasure coded implementation, it is assumed
in this design that providing > 16 disks is
a static configuration as well i.e if you started
the setup with 32 disks with 4 sets 8 disks per
pack then you would need to provide 4 sets always.

Some design details and restrictions:

- Objects are distributed using consistent ordering
  to a unique erasure coded layer.
- Each pack has its own dsync so locks are synchronized
  properly at pack (erasure layer).
- Each pack still has a maximum of 16 disks
  requirement, you can start with multiple
  such sets statically.
- Static sets set of disks and cannot be
  changed, there is no elastic expansion allowed.
- Static sets set of disks and cannot be
  changed, there is no elastic removal allowed.
- ListObjects() across sets can be noticeably
  slower since List happens on all servers,
  and is merged at this sets layer.

Aditya Manthramurthy a337ea4d11 Move admin APIs to new path and add redesigned heal APIs (#5351)
- Changes related to moving admin APIs
   - admin APIs now have an endpoint under /minio/admin
   - admin APIs are now versioned - a new API to server the version is
     added at "GET /minio/admin/version" and all API operations have the
     path prefix /minio/admin/v1/<operation>
   - new service stop API added
   - credentials change API is moved to /minio/admin/v1/config/credential
   - credentials change API and configuration get/set API now require TLS
     so that credentials are protected
   - all API requests now receive JSON
   - heal APIs are disabled as they will be changed substantially

- Heal API changes
   Heal API is now provided at a single endpoint with the ability for a
   client to start a heal sequence on all the data in the server, a
   single bucket, or under a prefix within a bucket.

   When a heal sequence is started, the server returns a unique token
   that needs to be used for subsequent 'status' requests to fetch heal
   results.

   On each status request from the client, the server returns heal result
   records that it has accumulated since the previous status request. The
   server accumulates upto 1000 records and pauses healing further
   objects until the client requests for status. If the client does not
   request any further records for a long time, the server aborts the
   heal sequence automatically.

   A heal result record is returned for each entity healed on the server,
   such as system metadata, object metadata, buckets and objects, and has
   information about the before and after states on each disk.

   A client may request to force restart a heal sequence - this causes
   the running heal sequence to be aborted at the next safe spot and
   starts a new heal sequence.
