Add the followng Ambari configuration options to support Kerberos token authentication

* {{authentication.kerberos.enabled}}
** Determines whether to use Kerberos (SPNEGO) authentication when connecting Ambari:  {{true}} to enable this feature; {{false}}, otherwise
* {{authentication.kerberos.spnego.principal}}
** The Kerberos principal name to use when verifying user-supplied Kerberos tokens for authentication via SPNEGO
* {{authentication.kerberos.spnego.keytab.file}}
** The Kerberos keytab file to use when verifying user-supplied Kerberos tokens for authentication via SPNEGO
* {{authentication.kerberos.user.types}}
** A comma-delimited (ordered) list of preferred user types to use when finding the Ambari user account for the user-supplied Kerberos identity during authentication via SPNEGO
* {{authentication.kerberos.auth_to_local.rules}}
** The auth-to-local rules set to use when translating a user's principal name to a local user name during authentication via SPNEGO.

NOTE: These properties are in the {{ambari.properties}} file since this feature may be enabled whether the rest of the cluster has Kerberos enabled or not.
