Add Consul support to 'OneClick' deployment.

The OOM is moving to using Consul to provide health checks for all ONAP
components.  This push adds deployment of a 3 node Consul Server cluster
and a single Consul agent to the 'OneClick' deployment.

As a first step, health check scripts for the A&AI microservices have
also been included.  Support for additional ONAP components will follow.
