bay-create should fail when docker fails to pull swarm image

[Janek Lehr]

Docker failed to pull the swarm image during bay creation because of a network issue, but the bay-create reported successful. It should report failure.

    Add wait condition on swarm services in swarm bay

    This blocks the heat stack from going into CREATE_COMPLETE status until
    all of the swarm services have completely started. This also means that
    if the swarm services fail to start, the bay will eventually timeout
    instead of going into CREATE_COMPLETE.
