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.

Andreas Auernhammer f6d0645a3c fix DoS vulnerability in the content SHA-256 processing (#8026)
This commit fixes a DoS issue that is caused by an incorrect
SHA-256 content verification during STS requests.

Before that fix clients could write arbitrary many bytes
to the server memory. This commit fixes this by limiting the
request body size.

Ensure that we use constants everywhere (#7845)
This allows for canonicalization of the strings
throughout our code and provides a common space
for all these constants to reside.

This list is rather non-exhaustive but captures
all the headers used in AWS S3 API operations

Add support for session policies in STS APIs (#7747)
This PR adds support for adding session policies
for further restrictions on STS credentials, useful
in situations when applications want to generate
creds for multiple interested parties with different
set of policy restrictions.

This session policy is not mandatory, but optional.

Fixes #7732

Harshavardhana 35d19a4ae2 Fix STS AssumeRole route conflict with MultipartUpload (#7574)
Since AssumeRole API was introduced we have a wrong route
match which results in certain clients failing to upload objects
using multipart because, multipart POST conflicts with STS POST
AssumeRole API.

Write a proper matcher function which verifies the route more
appropriately such that both can co-exist.

Migrate all Peer communication to common Notification subsystem (#7031)
Deprecate the use of Admin Peers concept and migrate all peer
communication to Notification subsystem. This finally allows
for a common subsystem for all peer notification in case of
distributed server deployments.

Harshavardhana 54ae364def Introduce STS client grants API and OPA policy integration (#6168)
This PR introduces two new features

- AWS STS compatible STS API named AssumeRoleWithClientGrants

```
POST /?Action=AssumeRoleWithClientGrants&Token=<jwt>
```

This API endpoint returns temporary access credentials, access
tokens signature types supported by this API

  - RSA keys
  - ECDSA keys

Fetches the required public key from the JWKS endpoints, provides
them as rsa or ecdsa public keys.

- External policy engine support, in this case OPA policy engine

- Credentials are stored on disks
