Allow use of onos docker for existing tests

- Allow Cluster to pull/build onos docker
- Connect clidriver to cli runnning in docker
- Some changes for debugability in components
- To use, set the useDocker and diffCliHosts tags in the cluster
  component to True, then define parameters in the params file
- Update all SR Stratum tests to use the tost docker image
- NOTE: Since the tost-onos image doesn't have openflow installe, we are
  currently only using docker for the bmv2 and tofino switches
