If the site replication is enabled and the code tries to extract jwt
claims while the site replication service account credentials are still
not loaded yet, the code will enter an infinite loop, causing in a
high CPU usage.
Another possibility of the infinite loop is having some service accounts
created by an old deployment version where the service account JWT was
signed by the root credentials, but not anymore.
This commit will remove the possibility of the infinite loop in the code
and add root credential fallback to extract claims from old service
accounts.
Also, sort the error map for multiple sites in ascending order
of deployment IDs, so that the error message generated is always
definitive order and same.

This change uses the updated ldap library in minio/pkg (bumped
up to v3). A new config parameter is added for LDAP configuration to
specify extra user attributes to load from the LDAP server and to store
them as additional claims for the user.
A test is added in sts_handlers.go that shows how to access the LDAP
attributes as a claim.
This is in preparation for adding SSH pubkey authentication to MinIO's SFTP
integration.

This commit adds support for MinKMS. Now, there are three KMS
implementations in `internal/kms`: Builtin, MinIO KES and MinIO KMS.
Adding another KMS integration required some cleanup. In particular:
- Various KMS APIs that haven't been and are not used have been
removed. A lot of the code was broken anyway.
- Metrics are now monitored by the `kms.KMS` itself. For basic
metrics this is simpler than collecting metrics for external
servers. In particular, each KES server returns its own metrics
and no cluster-level view.
- The builtin KMS now uses the same en/decryption implemented by
MinKMS and KES. It still supports decryption of the previous
ciphertext format. It's backwards compatible.
- Data encryption keys now include a master key version since MinKMS
supports multiple versions (~4 billion in total and 10000 concurrent)
per key name.

calling a remote target remove with a perfectly
well constructed ARN can lead to a crash for a bucket
with no replication configured.
This PR fixes, and adds a crash check for ImportMetadata
as well.
When importing access keys (i.e. service accounts) for LDAP accounts,
we are requiring groups to exist under one of the configured group base
DNs. This is not correct. This change fixes this by only checking for
existence and storing the normalized form of the group DN - we do not
return an error if the group is not under a base DN.
Test is updated to illustrate an import failure that would happen
without this change.
When LDAP is enabled, previously we were:
- rejecting creation of users and groups via the IAM import functionality
- throwing a `not a valid DN` error when non-LDAP group mappings are present
This change allows for these cases as we need to support situations
where the MinIO server contains users, groups and policy mappings
created before LDAP was enabled.
Create new code paths for multiple subsystems in the code. This will
make maintaing this easier later.
Also introduce bugLogIf() for errors that should not happen in the first
place.
Fix races in IAM cache
Fixes#19344
On the top level we only grab a read lock, but we write to the cache if we manage to fetch it.
a03dac41eb/cmd/iam-store.go (L446) is also flipped to what it should be AFAICT.
Change the internal cache structure to a concurrency safe implementation.
Bonus: Also switch grid implementation.
This change is to decouple need for root credentials to match between
site replication deployments.
Also ensuring site replication config initialization is re-tried until
it succeeds, this deoendency is critical to STS flow in site replication
scenario.
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.

to track the replication transfer rate across different nodes,
number of active workers in use and in-queue stats to get
an idea of the current workload.
This PR also adds replication metrics to the site replication
status API. For site replication, prometheus metrics are
no longer at the bucket level - but at the cluster level.
Add prometheus metric to track credential errors since uptime
- getObjectTagging to be allowed for anonymous policies
- return correct errors for invalid retention period
- return sorted list of tags for an object
- putObjectTagging must return 200 OK not 204 OK
- return 409 ErrObjectLockConfigurationNotAllowed for existing buckets
