By default the cpu load is the cumulative of all cores. Capture the
percentage load (load * 100 / cpu-count)
Also capture the percentage memory used (used * 100 / total)
use memory for async events when necessary and dequeue them as
needed, for all synchronous events customers must enable
```
MINIO_API_SYNC_EVENTS=on
```
Async events can be lost but is upto to the admin to
decide what they want, we will not create run-away number
of goroutines per event instead we will queue them properly.
Currently the max async workers is set to runtime.GOMAXPROCS(0)
which is more than sufficient in general, but it can be made
configurable in future but may not be needed.
there is potential for danglingWrites when quorum failed, where
only some drives took a successful write, generally this is left
to the healing routine to pick it up. However it is better that
we delete it right away to avoid potential for quorum issues on
version signature when there are many versions of an object.
it is okay if the warm-tier cannot keep up, we should continue
to take I/O at hot-tier, only fail hot-tier or block it when
we are disk full.
Bonus: add metrics counter for these missed tasks, we will
know for sure if one of the node is lagging behind or is
losing too many tasks during transitioning.
A disk that is not able to initialize when an instance is started
will never have a handler registered, which means a user will
need to restart the node after fixing the disk;
This will also prevent showing the wrong 'upgrade is needed.'
error message in that case.
When the disk is still failing, print an error every 30 minutes;
Disk reconnection will be retried every 30 seconds.

`OpMuxConnectError` was not handled correctly.
Remove local checks for single request handlers so they can
run before being registered locally.
Bonus: Only log IAM bootstrap on startup.

While healing the latest changes of expiry rules across sites
if target had pre existing transition rules, they were getting
overwritten as cloned latest expiry rules from remote site were
getting written as is. Fixed the same and added test cases as
well.

moveToTrash() function moves a folder to .trash, for example, when
doing some object deletions: a data dir that has many parts will be
renamed to the trash folder; However, ENOSPC is a valid error from
rename(), and it can cripple a user trying to free some space in an
entire disk situation.
Therefore, this commit will try to do a recursive delete in that case.
This allows batch replication to basically do not
attempt to copy objects that do not have read quorum.
This PR also allows walk() to provide custom
values for quorum under batch replication, and
key rotation.
