> Pre-configure (certain) services when Kerberos is enabled to reduce number of
> core service restarts when services are added.
> While processing the Kerberos descriptor, include services marked to be
> _pre-configured_. When a tagged service is encountered, process it weather
> it is installed or not. However if it is not installed, only apply
> configuration changes for existing configuration types. This will set at
> least the core-site changes related to proxyuser and auth-to-local rules
> properties. By doing this, if a tagged service is later installed, the
> settings will already be in place in the existing service configs and thus
> the existing services will not need to be restarted.
> Caveats:
> * Default values for the uninstalled, tagged, services will be assumed
> * The stack advisor will be used to suggest locations of components - used to
> build the clusterHostInfo structure that may be used to derive property
> values.
> Note: This processing is to occur when Kerberos is enabled.
