> Improve KDC integration by making the interfaces more consistent with each other.
> *Notes:*
> * When using the MIT KDC or IPA options, the {{kerberos-env/admin_server_host}} value *must be the fully qualified domain name* (FQDN) of the host were the KDC administrator service is. 
> * When connecting to the MIT KDC and IPA server, a username a password is not used to authenticate using the kadmin utility.  A Kerberos ticket is first acquired and that is used for authentication.
> * When creating Kerberos identities using the MIT KDC and IPA handlers, the Ambari-generated password is not used.  All password's for principals in the MIT KDC and IP server are generated randomly by the KDC.
> * Removed {{kerberos-env/set_password_expiry}} and {{kerberos-env/password_chat_timeout}} properties since they are no longer needed
> * Changed {{kerberos-env/groups}} to {{kerberos-env/ipa_user_groups}} to be more explicit in how the property is used.
> * The setPassword implementation for the MIT KDC and IPA handlers do nothing except check to see if the relevant principal exists. This is to maintain backward compatibility with previous implementations.
