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: support healing older content (#10076)
This PR adds support for healing older
content i.e from 2yrs, 1yr. Also handles
other situations where our config was
not encrypted yet.

This PR also ensures that our Listing
is consistent and quorum friendly,
such that we don't list partial objects

fix: add virtual host style workaround for gorilla/mux issue (#10010)
gorilla/mux broke their recent release 1.7.4 which we
upgraded to, we need the current workaround to ensure
that our regex matches appropriately.

An upstream PR is sent, we should remove the
workaround once we have a new release.

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: load LDAP users appropriately (#9360)
This PR also fixes issues when

deletePolicy, deleteUser is idempotent so can lead to
issues when client can prematurely timeout, so a retry
call error response should be ignored when call returns
http.StatusNotFound

Add rate limiter for S3 API layer (#9196)
- total number of S3 API calls per server
- maximum wait duration for any S3 API call

This implementation is primarily meant for situations
where HDDs are not capable enough to handle the incoming
workload and there is no way to throttle the client.

This feature allows MinIO server to throttle itself
such that we do not overwhelm the HDDs.

reference format obtained doesn't need further validation (#8964)
we don't need to validateFormats again once we have obtained
reference format, because it is possible that at this stage
another server is doing a disk heal during startup, once
in a while due to delays we get false positives and our
server doesn't start.

Format in quorum as reference format can be assumed as valid
and we proceed further, until and unless HealFormat re-inits
the disks after a successful heal.

Also use separate port for healing tests to avoid any
conflicts with regular build testing.

Harshavardhana 822eb5ddc7 Bring in safe mode support (#8478)
This PR refactors object layer handling such
that upon failure in sub-system initialization
server reaches a stage of safe-mode operation
wherein only certain API operations are enabled
and available.

This allows for fixing many scenarios such as

 - incorrect configuration in vault, etcd,
   notification targets
 - missing files, incomplete config migrations
   unable to read encrypted content etc
 - any other issues related to notification,
   policies, lifecycle etc

Harshavardhana d28bcb4f84 Migrate all backend at .minio.sys/config to encrypted backend (#8474)
- Supports migrating only when the credential ENVs are set,
  so any FS mode deployments which do not have ENVs set will
  continue to remain as is.
- Credential ENVs can be rotated using MINIO_ACCESS_KEY_OLD
  and MINIO_SECRET_KEY_OLD envs, in such scenarios it allowed
  to rotate the encrypted content to a new admin key.

Harshavardhana 9e7a3e6adc Extend further validation of config values (#8469)
- This PR allows config KVS to be validated properly
  without being affected by ENV overrides, rejects
  invalid values during set operation

- Expands unit tests and refactors the error handling
  for notification targets, returns error instead of
  ignoring targets for invalid KVS

- Does all the prep-work for implementing safe-mode
  style operation for MinIO server, introduces a new
  global variable to toggle safe mode based operations
  NOTE: this PR itself doesn't provide safe mode operations

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.

Avoid error modification during IAM migration (#8156)
The underlying errors are important, for IAM
requirements and should wait appropriately at
the caller level, this allows for distributed
setups to run properly and not fail prematurely
during startup.
