Properly replicate policy mapping for virtual users (#15558)
Currently, replicating policy mapping for STS users does not work. Fix
it is by passing user type to PolicyDBSet.

Remove internal usage of consoleAdmin (#15402)
"consoleAdmin" was used as the policy for root derived accounts, but this
lead to unexpected bugs when an administrator modified the consoleAdmin
policy

This change avoids evaluating a policy for root derived accounts as by
default no policy is mapped to the root user. If a session policy is
attached to a root derived account, it will be evaluated as expected.

feat: Single drive XL implementation (#14970)
Main motivation is move towards a common backend format
for all different types of modes in MinIO, allowing for
a simpler code and predictable behavior across all features.

This PR also brings features such as versioning, replication,
transitioning to single drive setups.

Merge LDAP STS policy evaluation with the generic STS code (#14944)
If LDAP is enabled, STS security token policy is evaluated using a
different code path and expects ldapUser claim to exist in the security
token. This means other STS temporary accounts generated by any Assume
Role function, such as AssumeRoleWithCertificate, won't be allowed to do any
operation as these accounts do not have LDAP user claim.

Since IsAllowedLDAPSTS() is similar to IsAllowedSTS(), this commit will
merge both.

Non harmful changes:
- IsAllowed for LDAP will start supporting RoleARN claim
- IsAllowed for LDAP will not check for parent claim anymore. This check doesn't
  seem to be useful since all STS login compare access/secret/security-token
  with the one saved in the disk.
- LDAP will support $username condition in policy documents.

allow IAM cache load to be granular and capture missed state (#14930)
anything that is stuck on the disk today can cause latency
spikes for all incoming S3 I/O, we need to have this
de-coupled so that we can make sure that latency in loading
credentials are not reflected back to the S3 API calls.

The approach this PR takes is by checking if the calls were
updated just in case when the IAM load was in progress,
so that we can use merge instead of "replacement" to avoid
missing state.

Add support for Access Management Plugin (#14875)

OPA specific configuration is marked as deprecated.

fix: remove embedded-policy as requested by the user (#14847)
this PR introduces a few changes such as

- sessionPolicyName is not reused in an extracted manner
  to apply policies for incoming authenticated calls,
  instead uses a different key to designate this
  information for the callers.

- this differentiation is needed to ensure that service
  account updates do not accidentally store JSON representation
  instead of base64 equivalent on the disk.

- relax requirements for Deleting a service account, allow
  deleting a service account that might be unreadable, i.e
  a situation where the user might have removed session policy 
  which now carries a JSON representation, making it unparsable.

- introduce some constants to reuse instead of strings.

decouple service accounts from root credentials (#14534)
changing root credentials makes service accounts
in-operable, this PR changes the way sessionToken
is generated for service accounts.

It changes service account behavior to generate
sessionToken claims from its own secret instead
of using global root credential.

Existing credentials will be supported by
falling back to verify using root credential.

Add internal IDP and OIDC users support for site-replication (#14041)
- This allows site-replication to be configured when using OpenID or the
  internal IDentity Provider.

- Internal IDP IAM users and groups will now be replicated to all members of the
  set of replicated sites.

- When using OpenID as the external identity provider, STS and service accounts
  are replicated.

- Currently this change dis-allows root service accounts from being
  replicated (TODO: discuss security implications).

fix: initialize new drwMutex for each attempt in 'for {' loop. (#14009)
It is possible that GetLock() call remembers a previously
failed releaseAll() when there are networking issues, now
this state can have potential side effects.

This PR tries to avoid this side affect by making sure
to initialize NewNSLock() for each GetLock() attempts
made to avoid any prior state in the memory that can
interfere with the new lock grants.

Fix user privilege escalation bug (#13976)
The AddUser() API endpoint was accepting a policy field. 
This API is used to update a user's secret key and account 
status, and allows a regular user to update their own secret key. 

The policy update is also applied though does not appear to 
be used by any existing client-side functionality.

This fix changes the accepted request body type and removes 
the ability to apply policy changes as that is possible via the 
policy set API.

NOTE: Changing passwords can be disabled as a workaround
for this issue by adding an explicit "Deny" rule to disable the API
for users.

Map policy to parent for STS (#13884)
When STS credentials are created for a user, a unique (hopefully stable) parent
user value exists for the credential, which corresponds to the user for whom the
credentials are created. The access policy is mapped to this parent-user and is
persisted. This helps ensure that all STS credentials of a user have the same
policy assignment at all times.

Before this change, for an OIDC STS credential, when the policy claim changes in
the provider (when not using RoleARNs), the change would not take effect on
existing credentials, but only on new ones.

To support existing STS credentials without parent-user policy mappings, we
lookup the policy in the policy claim value. This behavior should be deprecated
when such support is no longer required, as it can still lead to stale
policy mappings.

Additionally this change also simplifies the implementation for all non-RoleARN
STS credentials. Specifically, for AssumeRole (internal IDP) STS credentials,
policies are picked up from the parent user's policies; for
AssumeRoleWithCertificate STS credentials, policies are picked up from the
parent user mapping created when the STS credential is generated.
AssumeRoleWithLDAP already picks up policies mapped to the virtual parent user.
