Two enhancements:

1. Configuration of collectD : some agent that sits along collectD to read configuration from Consul and configures collectD.
2. Advertisement of collectD end points :  Agent to advertize collectD reachability information in Consul. (Assumption is that collectd is configured in pull mode)

This work need to be done outside of ONAP. But it needs to be coordinated.

This work might need to happen in OPNFV barometer project.
