Since relaxing quorum the error across pools
for ListBuckets(), GetBucketInfo() we hit a
situation where loading IAM could potentially
return an error for second pool that server
is not initialized.
We need to handle this, let the pool come online
and retry transparently - this PR fixes that.
x-amz-signed-headers is meant for HTTP headers only
not for query params, using that to verify things
further can lead to failure.
The generated presigned URL with custom metadata
is already kosher (tamper proof).

`resourceMetricsMap` has no protection against concurrent reads and writes.
Add a mutex and don't use maps from the last iteration.
Bug introduced in #18057Fixes#18271
globalDeploymentID was being read while it was being set.
Fixes race:

currently the default for all drives is 512, which is a lot
for HDDs the recent testing has revealed moving this to 32
for HDDs seems like a fair value.
Introducing a new version of healthinfo struct for adding this info is
not correct. It needs to be implemented differently without adding a new
version.
This reverts commit 8737025d940f80360ed4b3686b332db5156f6659.
There is a fundamental race condition in `newErasureServerPools`, where setObjectLayer is
called before the poolMeta has been loaded/populated.
We add a placeholder value to this field but disable all saving of the value, so we don't risk
overwriting the value on disk. Once the value has been loaded or created, it is replaced with
the proper value, which will also be saved.
Also fixes various accesses of `poolMeta` that were done without locks.
We make the `poolMeta.IsSuspended` return false, even if we shouldn't risk out-of-bounds
reads anymore.
if erasure upgrade is needed rely on the in-memory
values, instead of performing a "DiskInfo()" call.

for HDDs these are problematic, lets avoid this because
there is no value in "being" absolutely strict here
in terms of parity. We are okay to increase parity
as we see based on the in-memory online/offline ratio.
Several callers to putObjectTar may be fighting to set sc. Move the write out of the loop.
Use static resp, and request elements.
Fixes tests with -race:
