Add better error handling on Zulip (#1589)

Browse Source 
* zulip: Treat unknown errors with a 10-second backoff.

An unknown error (including an unauthorized error) would fall through
with no calls to time.Sleep, resulting in hammering the server as
quickly as possible.

Add a 10-second sleep in the default error case.  The heartbeat is
left with no explicit sleep, but all other codepaths now contain one.

* version: Move version information into a separate package.

This will allow it to be accessed by other sections of the code.

* zulip: Use the matterbridge version in the user-agent.
