entrypoint: add --mirror-state option 

The --mirror-state option specifies a path to a file in which the script
will record the state of (rbd) mirroring. This can then later be reused
in order to skip the somewhat time consuming mirroring setup if the
statefile indicates mirroring is already functional.
