  - Fix NPE in PushResultProcessing
    
    The PushOne code passes a null to the notifier on cleanup when it
    encounters unknown states and this null gets passed all the way to
    PushResultProcessing which previously would NPE on it. Handle the null
    by outputting an "unknown" instead of crashing.

  - Fix start --wait to track in-flight collisions and to not fail
    
    Previously when an in-flight collision occurred on a push that the
    'start --wait' command  was waiting for, the command would terminate
    with an error (and if it weren't for an NPE it would stop waiting
    prematurely). This was happening because PushOne is not tracking
    collisions resulting in its cleanup code assuming there was a failure.
    Fix this by tracking the collision in PushOne and skipping the cleanup
    in this case.
    
    Ironically, the NPE in change I107d964a33349aaa5d6ae9aca68aab2889689155
    was preventing the start command from receiving the premature
    termination on the collision, but it was not preventing the error. Thus
    this fix should get merged before fixing the NPE to avoid a worse
    scenario.

    Bug: Issue 12719
    
  - Improve URLmatching to match real Urls
    
    Previously the UrlMatch string needed to match the templated value in
    the replication.config file, now it can additionally match a real URL
    with the project name already in it.

  - Convert PushResultProcessing to an interface
    
    Instead of being an abstract class with methods that must be explicitly
    overridden (even if they are no-op), convert it to an interface with
    default empty methods. Also introduce a NO_OP instance. This allows to
    have implementations that do nothing without having to explicitly add
    all the boilerplate overrides.
