removes contentious usage of mutexes in LRU, which
were never really reused in any manner; we do not
need it.
To trust hosts, the correct way is TLS certs; this PR completely
removes this dependency, which has never been useful.

Bonus: use `x-minio-time` as a nanosecond to avoid unnecessary
parsing logic of time strings instead of using a more
straightforward mechanism.
- Also, fix failure reporting at the end.
- Also, avoid parsing report objects when listing or resuming jobs, this
does not cause any bugs, it is only printing, not useful errors.
add unit test for v3 metrics for all its exposed endpoints
Bonus:
- support OpenMetrics encoding
- adds boot time for prometheus
- continueOnError is better to serve as
much metrics as possible.
```
curl http://localhost:9000/minio/metrics/v3/cluster/usage/buckets
```
Did not work as documented, due to the fact that there was a typo
in the bucket usage metrics registration group. This endpoint is
a cluster endpoint and does not require any `buckets` argument.
When creating the async listing, if the first request does not return within 3
minutes, it is stopped, since it isn't being kept alive.
Keep updating `lastHandout` while we are waiting for the initial request to be fulfilled.
When a fresh drive healing is finished, add more checks for the drive listing
errors. If any, re-list and heal again. Although this is an infrequent use
case to have listPathRaw() returning nil when minDisks is set to 1, we
still need to handle all possible use cases to avoid missing healing
any object.
Also, check for HealObject result to decide of an object is healed in the
fresh disk since HealObject returns nil if an object is healed in any
disk, and not in the new fresh drive.
In regular listing, this commit will avoid showing an object when its
latest version has a pending or failed deletion. In replicated setup.
It will also prevent showing older versions in the same case.
Also, sort the error map for multiple sites in ascending order
of deployment IDs, so that the error message generated is always
definitive order and same.

Add `ConnDialer` to abstract connection creation.
- `IncomingConn(ctx context.Context, conn net.Conn)` is provided as an entry point for
incoming custom connections.
- `ConnectWS` is provided to create web socket connections.
If `SkipReader` is called with a small initial buffer it may be doing a huge number if Reads to skip the requested number of bytes. If a small buffer is provided grab a 32K buffer and use that.
Fixes slow execution of `testAPIGetObjectWithMPHandler`.
Bonuses:
* Use `-short` with `-race` test.
* Do all suite test types with `-short`.
* Enable compressed+encrypted in `testAPIGetObjectWithMPHandler`.
* Disable big file tests in `testAPIGetObjectWithMPHandler` when using `-short`.
The code was advertenly passing max openfds to debug.SetMemoryLimit(),
fixing this accelerate go test in my machine.
This is only a testing bug, since the server context has always a valid
MaxMem, so the buggy code was never called in users environments.
Currently the status of a completed or failed batch is held in the
memory, a simple restart will lose the status and the user will not
have any visibility of the job that was long running.
In addition to the metrics, add a new API that reads the batch status
from the drives. A batch job will be cleaned up three days after
completion.
Also add the batch type in the batch id, the reason is that the batch
job request is removed immediately when the job is finished, then we
do not know the type of batch job anymore, hence a difficulty to locate
the job report
Hot load a policy document when during account authorization evaluation
to avoid returning 403 during server startup, when not all policies are
already loaded.
Add this support for group policies as well.
you can attempt a rebalance first i.e, start with 2 pools.
```
mc admin rebalance start alias/
```
and after that you can add a new pool, this would
potentially crash.
