Fix runtestmanager for CICD deployments

In CICD deployments, there are no workarounds that install
docker.io before using 'runtest' formula.
Add preparation of necessary packages to runtestmanager.

- Refactor RuntestManager to use salt CLI instead of salt API
  because salt API dones't allow to catch errors from modules
- Add preparations for docker packages, Neutron private and
  public networks based on underlay.yaml address pools, etc.
