This commit reuses the existing infrastructure for moving a topic
within a stream to add support for moving topics from one stream to
another.
Split from the original full-feature commit so that we can merge just
the backend, which is finished, at this time.
This is a large part of #6427.
The feature is incomplete, in that we don't have real-time update of
the frontend to handle the event, documentation, etc., but this commit
is a good mergable checkpoint that we can do further work on top of.
We also still ideally would have a test_events test for the backend,
but I'm willing to leave that for follow-up work.
This appears to have switched to tabbott as the author during commit
squashing sometime ago, but this commit is certainly:

This is preparation for supporting moving messages between streams in
some cases.
It doesn't actually have any functional effect, since flush_message
clears the message unconditionally anyway.
This limit was introduced in c588c79 as a part of the
feature and not due to performance crisis. So we are
increasing this limit to 7 days. Since topics tends to
naturally fizzle after day or two so 7 days limit
would be good enough.
Fixes#1727.
With the server down, apply migrations 0245 and 0246. 0246 will remove
the pub_date column, so it's essential that the previous migrations
ran correctly to copy data before running this.
This seems like kind of a silly function to extract
to topic.py, but it will theoretically help us sweep
"subject" if we change the DB.
It had test coverage.
We (lexically) remove "subject" from the conversion code. The
`build_message` helper calls `set_topic_name` under the hood,
so things still have "subject" in the JSON.
There was good code coverage on `build_message`.
This is somewhat hairy logic, so it's nice
to extract it and not worry about variable leaks.
Also, this moves some legacy "subject" references out
of actions.py.
We start by including functions that do custom
queries for topic history.
The goal of this library is partly to quarantine
the legacy "subject" column on Message.
