ldap: Add user DN attributes list config param (#19758)

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.
