initialize IAM as soon as object layer is initialized (#10700)
Allow requests to come in for users as soon as object
layer and config are initialized, this allows users
to be authenticated sooner and would succeed automatically
on servers which are yet to fully initialize.

Bump default idleConnsPerHost to control conns in time_wait (#10653)
This PR fixes a hang which occurs quite commonly at higher concurrency
by allowing following changes

- allowing lower connections in time_wait allows faster socket open's
- lower idle connection timeout to ensure that we let kernel
  reclaim the time_wait connections quickly
- increase somaxconn to 4096 instead of 2048 to allow larger tcp
  syn backlogs.

fixes #10413

remove safeMode behavior in startup (#10645)
In almost all scenarios MinIO now is
mostly ready for all sub-systems
independently, safe-mode is not useful
anymore and do not serve its original
intended purpose.

allow server to be fully functional
even with config partially configured,
this is to cater for availability of actual
I/O v/s manually fixing the server.

In k8s like environments it will never make
sense to take pod into safe-mode state,
because there is no real access to perform
any remote operation on them.

Tweaks to dynamic locks (#10508)
* Fix cases where minimum timeout > default timeout.
* Add defensive code for too small/negative timeouts.
* Never set timeout below the maximum value of a request.
* Protect against (unlikely) int64 wraps.
* Decrease timeout slower.
* Don't re-lock before copying.

use single dynamic timeout for most locked API/heal ops (#10275)
newDynamicTimeout should be allocated once, in-case
of temporary locks in config and IAM we should
have allocated timeout once before the `for loop`

This PR doesn't fix any issue as such, but provides
enough dynamism for the timeout as per expectation.

feat: allow service accounts to be generated with OpenID STS (#10184)
Bonus also fix a bug where we did not purge relevant
service accounts generated by rotating credentials
appropriately, service accounts should become invalid
as soon as its corresponding parent user becomes invalid.

Since service account themselves carry parent claim always
we would never reach this problem, as the access get
rejected at IAM policy layer.

fix: Pass context all the way down to the network call in lockers (#10161)
Context timeout might race on each other when timeouts are lower
i.e when two lock attempts happened very quickly on the same resource
and the servers were yet trying to establish quorum.

This situation can lead to locks held which wouldn't be unlocked
and subsequent lock attempts would fail.

This would require a complete server restart. A potential of this
issue happening is when server is booting up and we are trying
to hold a 'transaction.lock' in quick bursts of timeout.

allow claims to be optional in STS (#10078)
not all claims need to be present for
the JWT claim, let the policies not
exist and only apply which are present
when generating the credentials

once credentials are generated then
those policies should exist, otherwise
the request will fail.

Support bucket versioning (#9377)
- Implement a new xl.json 2.0.0 format to support,
  this moves the entire marshaling logic to POSIX

fix: remove LDAP groups claim and store them on server (#9637)
Groups information shall be now stored as part of the
credential data structure, this is a more idiomatic
way to support large LDAP groups.

Avoids the complication of setups where LDAP groups
can be in the range of 150+ which may lead to excess
HTTP header size > 8KiB, to reduce such an occurrence
we shall save the group information on the server as
part of the credential data structure.

Bonus change support multiple mapped policies, across
all types of users.

fix: deprecate requirement of session token for service accounts (#9320)
This PR fixes couple of behaviors with service accounts

- not need to have session token for service accounts
- service accounts can be generated by any user for themselves
  implicitly, with a valid signature.
- policy input for AddNewServiceAccount API is not fully typed
  allowing for validation before it is sent to the server.
- also bring in additional context for admin API errors if any
  when replying back to client.
- deprecate GetServiceAccount API as we do not need to reply
  back session tokens
