We can descope this ticket to perform connectivity check (host:port) from only
ambari-server host to KDC server host as the first step in this direction. This
check will validate that KDC host is reachable and resolvable from
ambari-server host and daemon is running on KDC port (user specified) on KDC
host (user specified).
> Implement custom command for checking connectivity to KDC, via REST API

> There needs to be a way, given the details about a KDC to verify that Ambari
> and (optionally) the nodes in the existing cluster can connect to it.
> From the cluster hosts, this test should test that the address and port
> combinations are reachable.
> From the Ambari server, this test should make sure the administrator
> credentials allow at least read access to the KDC.
> As an example of a similar action, see how Oozie does this for DB check pre
> install.
