Subject: Add activity expirations table

Add a table to store activity expirations. An activity can have zero or
one expirations. The expiration has a scheduled_at field which stores
the time at which the activity should expire and be deleted.

Subject: Add support for activity expiration to common and Masto API

The "expires_at" parameter accepts an ISO8601-formatted date which
defines when the activity will expire.

At this point the API will not give you any feedback about if your post
will expire or not.

Subject: Require that ephemeral posts live for at least one hour

If we didn't put some kind of lifetime requirement on these, I guess you
could annoy people by sending large numbers of ephemeral posts that
provoke notifications but then disappear before anyone can read them.

Subject: Expose expires_at datetime in mastoAPI only for the activity actor

In the "pleroma" section of the MastoAPI for status activities you can
see an expires_at item that states when the activity will expire, or
nothing if the activity will not expire.

The expires_at date is only visible to the person who posted the
activity. This is the conservative approach in case some attacker
decides to write a logger for expiring posts. However, in the future of
OCAP, signed requests, and all that stuff, this attack might not be that
likely. Some other pleroma dev should remove the restriction in the code
at that time, if they're satisfied with the security implications of
doing so.
