fix: allow STS credentials with dynamic policies (#12681)
- ParentUser for OIDC auth changed to `openid:`
  instead of `jwt:` to avoid clashes with variable
  substitution

- Do not pass in random parents into IsAllowed()
  policy evaluation as it can change the behavior
  of looking for correct policies underneath.

fix: etcd IAM encryption fails due to incorrect kms.Context (#12431)

the migration by not migrating STS users instead let the
clients regenerate them.

lock: Always cancel the returned Get(R)Lock context (#12162)
* lock: Always cancel the returned Get(R)Lock context

There is a leak with cancel created inside the locking mechanism. The
cancel purpose was to cancel operations such erasure get/put that are
holding non-refreshable locks.

This PR will ensure the created context.Cancel is passed to the unlock
API so it will cleanup and avoid leaks.

* locks: Avoid returning nil cancel in local lockers

Since there is no Refresh mechanism in the local locking mechanism, we
do not generate a new context or cancel. Currently, a nil cancel
function is returned but this can cause a crash. Return a dummy function
instead.

IAM: Block while loading users (#11671)
While starting up a request that needs all IAM data will start another load operation if the first on startup hasn't finished. This slows down both operations.

Block these requests until initial load has completed.

Blocking calls will be ListPolicies, ListUsers, ListServiceAccounts, ListGroups - and the calls that eventually trigger these. These will wait for the initial load to complete.

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.

Fix policy setting error in LDAP setups (#9303)
Fixes #8667

In addition to the above, if the user is mapped to a policy or 
belongs in a group, the user-info API returns this information, 
but otherwise, the API will now return a non-existent user error.

Aditya Manthramurthy a0456ce940 LDAP STS API (#8091)
Add LDAP based users-groups system

This change adds support to integrate an LDAP server for user
authentication. This works via a custom STS API for LDAP. Each user
accessing the MinIO who can be authenticated via LDAP receives
temporary credentials to access the MinIO server.

LDAP is enabled only over TLS.

User groups are also supported via LDAP. The administrator may
configure an LDAP search query to find the group attribute of a user -
this may correspond to any attribute in the LDAP tree (that the user
has access to view). One or more groups may be returned by such a
query.

A group is mapped to an IAM policy in the usual way, and the server
enforces a policy corresponding to all the groups and the user's own
mapped policy.

When LDAP is configured, the internal MinIO users system is disabled.

This PR adds pass-through, single encryption at gateway and double
encryption support (gateway encryption with pass through of SSE

If KMS is set up (either with Vault as KMS or using
MINIO_SSE_MASTER_KEY),gateway will automatically perform
single encryption. If MINIO_GATEWAY_SSE is set up in addition to
Vault KMS, double encryption is performed.When neither KMS nor
MINIO_GATEWAY_SSE is set, do a pass through to backend.

When double encryption is specified, MINIO_GATEWAY_SSE can be set to
"C" for SSE-C encryption at gateway and backend, "S3" for SSE-S3
encryption at gateway/backend or both to support more than one option.
