Don't permit users to run repo status in a mirror client
If a client was created with "repo init --mirror" then there are
no working directories present, and no files checked out. Using
a command like "repo status" in this context makes no sense, and
actually throws back a Pytyon traceback at the console when the
underlying commands fail out.
We now tag commands with the MirrorSafeCommand type if they are
able to be executed within a mirror directory safely. Using a
command in a mirror which lacks this base class results in a
useful error letting you know the command isn't supported.
