expire, trust et al, dead, describe: Support --json and --json-error-messages
For expire, the normal output is unchanged, but the --json output includes the uuid
in machine parseable form. Which could be very useful for this somewhat obscure
command. That needed ActionItemUUID to be implemented, which seemed like a lot
of work, but then ---

I had been going to skip implementing them for trust, untrust, dead, semitrust,
and describe, but putting the uuid in the json is useful information, it tells
what uuid git-annex picked given the input. It was not hard to support
these once ActionItemUUID was implemented.
