Kibana wants to create access_token/refresh_token pair using Token management APIs in exchange for kerberos tickets. `client_credentials` grant_type requires every user to have `cluster:admin/xpack/security/token/create` cluster privilege. This commit introduces `kerberos` grant_type for generating `access_token` and `refresh_token` in exchange for a valid base64 encoded kerberos ticket. In addition, `kibana_user` role now has cluster privilege to create tokens. This allows Kibana to create access_token/refresh_token pair in exchange for kerberos tickets. Note: The lifetime from the kerberos ticket is not used in ES and so even after it expires the access_token/refresh_token pair will be valid. Care must be taken to invalidate such tokens using token management APIs if required. TODO: - The `KerberosAuthenticationIT` requires krb5-kdc fixture to be enabled, currently it is disabled. This will be fixed in another commit. - Documentation
