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.

specifying customer HTTP client makes the gcs SDK

SDK manage the transport.
this PR fixes#19922 a regression from #19565
Currently, bucket metadata is being loaded serially inside ListBuckets
Objet API. Fix that by loading the bucket metadata as the number of
erasure sets * 10, which is a good approximation.
since the connection is active, the
response recorder body can grow endlessly
causing leak, as this bytes buffer is
never given back to GC due to an goroutine.
skip healing properly in scanner when drive is hotplugged
due to how the state is passed around the SkipHealing
might not be the true state() of the system always, causing
a situation where we might healing from the scanner on the
same drive which is being. Due to this competing heals get
triggered that slow each other down.
due to a historic bug in CopyObject() where
an inlined object loses its metadata, the
check causes an incorrect fallback verifying
data-dir.
CopyObject() bug was fixed in ffa91f9794 however
the occurrence of this problem is historic, so
the aforementioned check is stretching too much.
Bonus: simplify fileInfoRaw() to read xl.json as well,
also recreate buckets properly.
* Multipart SSEC checksums were not transferred.
* Remove key mismatch logging. This key is user-controlled with SSEC.
* If the source is SSEC and the destination reports ErrSSEEncryptedObject,
assume replication is good.
avoid concurrent callers for LoadUser() to even initiate
object read() requests, if an on-going operation is in progress.
this avoids many callers hitting the drives causing I/O
spikes, also allows for loading credentials faster.
the reason for this is to avoid STS mappings to be
purged without a successful load of other policies,
and all the credentials only loaded successfully
are properly handled.
This also avoids unnecessary cache store which was
implemented earlier for optimization.
Directory objects are used by applications that simulate the folder
structure of an on-disk filesystem. These are zero-byte objects with names
ending with '/'. They are only used to check whether a 'folder' exists in
the namespace.
StartSize starts with the raw free space of all disks in the given pool,
however during the status, CurrentSize is not showing the current free
raw space, as expected at least by `mc admin decom status` since it was
written.
