Authorization Realms allow an authenticating realm to delegate the task
of constructing a User object (with name, roles, etc) to one or more
other realms.
E.g. A client could authenticate using PKI, but then delegate to an LDAP
realm. The LDAP realm performs a "lookup" by principal, and then does
regular role-mapping from the discovered user.
This commit includes:
- authorization_realm support in the pki, ldap, saml & kerberos realms
- docs for authorization_realms
- checks that there are no "authorization chains"
(whereby "realm-a" delegates to "realm-b", but "realm-b" delegates to "realm-c")
Authorization realms is a platinum feature.
Add documentation for #31238
- Add documentation for the req_authn_context_class_ref setting
- Add a section in SAML Guide regarding the use of SAML
Authentication Context.
* Add relevant documentation for FIPS 140-2 compliance.

* [DOCS] Add configurable password hashing docs
Adds documentation about the newly introduced configuration option
for setting the password hashing algorithm to be used for the users
cache and for storing credentials for the native and file realm.
This commit adds documentation for configuring Kerberos realm.
Configuring Kerberos realm documentation highlights important
terminology and requirements before creating Kerberos realm.
Most of the documentation is centered around configuration from
Elasticsearch rather than go deep into Kerberos implementation.
Kerberos realm settings are mentioned in the security settings
for Kerberos realm.
