  - Consistently handle remote repository creation failures
    
    Failure to create remote repository was handled inconsistently in the
    three existing AdminApi implementations. This issue was present in the
    code even before the refactoring done in
    Ie760bf3e143b1d143b6e81ac6cfa816ef1f8d016. For example, creation of
    remote repository over SSH [1] didn't return a status back to the
    caller, while the Gerrit+SSH implementation [2] did return a boolean
    flag which was afterwards ignored by the caller [3].
    
    Not handling remote repository creation failures had an ugly effect:
    we log the "Missing repository created; ..." [4], even if the repository
    creation failed.
    
    Let all three implementations of the AdminApi return a flag indicating
    the success/failure and make sure to handle it properly.
    
    Further, remove some redundant and potentially confusing parts of the
    log messages as they assume that failure to create missing repository
    can only be caused by using wrong protocol.
