Integrate with Ambari cluster manager

Trafodion should be installable via Ambari. We can create an extension or management pack that would plug into ambari.

The trafodion management commands (sqstart, sqstop, sq...) currently work across cluster via required ssh access. Eventually, we should get away from that, but in the mean time we can define a component/role on a single node to run these commands.

Current installer also does not fit into the required architecture to run installation node-by-node. That needs to be re-factored, so that command-line install can share code with cluster-manager (e.g., ambari) install.
