This PR improves the replication failure healing by persisting
most recent failures to disk and re-queuing them until the replication
is successful.
While this does not eliminate the need for healing during a full scan,
queuing MRF vastly improves the ETA to keeping replicated buckets
in sync as it does not wait for the scanner visit to detect unreplicated
object versions.
competing calls on the same object on versioned bucket
mutating calls on the same object may unexpected have
higher delays.
This can be reproduced with a replicated bucket
overwriting the same object writes, deletes repeatedly.
For longer locks like scanner keep the 1sec interval
This PR fixes possible leaks that may emanate from not
listening on context cancelation or timeouts.

The bottom line is delete markers are a nuisance,
most applications are not version aware and this
has simply complicated the version management.
AWS S3 gave an unnecessary complication overhead
for customers, they need to now manage these
markers by applying ILM settings and clean
them up on a regular basis.
To make matters worse all these delete markers
get replicated as well in a replicated setup,
requiring two ILM settings on each site.
This PR is an attempt to address this inferior
implementation by deviating MinIO towards an
idempotent delete marker implementation i.e
MinIO will never create any more than single
consecutive delete markers.
This significantly reduces operational overhead
by making versioning more useful for real data.
This is an S3 spec deviation for pragmatic reasons.
Queue failed/pending replication for healing during listing and GET/HEAD
API calls. This includes healing of existing objects that were never
replicated or those in the middle of a resync operation.
This PR also fixes a bug in ListObjectVersions where lifecycle filtering
should be done.
when object speedtest is running keep writing
previous speedtest result back to client until
we have a new result - this avoids sending back
blank entries in between the speedtest when it
is running in 'autotune' mode.

Update on-disk storage format for users system (#7949)
```
Bonus: fixes a bug when etcd keys were being re-encrypted.
Currently, the code doesn't check if the user creating a bucket with
locking feature has bucket locking and versioning permissions enabled,
adding it in accordance with S3 spec.
https://docs.aws.amazon.com/AmazonS3/latest/API/API_CreateBucket.html
Object Lock - If ObjectLockEnabledForBucket is set to true in your CreateBucket request,
s3:PutBucketObjectLockConfiguration and s3:PutBucketVersioning permissions are required.
Capture average, p50, p99, p999 response times
and ttfb values. These are needed for latency
measurements and overall understanding of our
speedtest results.
listConfigItems creates a goroutine but sometimes callers will
exit without properly asking listAllIAMConfigItems() to stop sending
results, hence a goroutine leak.
Create a new context and cancel it for each listAllIAMConfigItems
call.
This commit adds support for automatically reloading
the MinIO client certificate for authentication to KES.
The client certificate will now be reloaded:
- when the private key / certificate file changes
- when a SIGHUP signal is received
- every 15 minutes
Fixes#14869

The path is marked dirty automatically when healObject() is called, which is
wrong. HealObject() is called during self-healing and this will lead to
an increase in the false positive result of the bloom filter.
Also move NSUpdated() from renameData() and call it directly in
CompleteMultipart and PutObject, this is not a functional change but
it will make it less prone to errors in the future.
smaller setups may have less drives per server choosing
the concurrency based on number of local drives, and let
the MinIO server change the overall concurrency as
necessary.
It is possible for anyone with admin access to relatively
to get any content of any random OS location by simply
providing the file with 'mc admin update alias/ /etc/passwd`.
Workaround is to disable 'admin:ServiceUpdate' action. Everyone
is advised to upgrade to this patch.
Thanks to @alevsk for finding this bug.
