Certbot replaces the cert files under /etc/letsencrypt/live/,
which our nginx config refers to symlinks to; but it doesn't
tell nginx there's been an update, so nginx keeps serving the
old cert.
This is fine as long as nginx is restarted, or just told to
reload its config, at some point before the cert actually
expires about 30 days later. Which is probably the common
case, but of course we should make it just work. So, if we
actually renew a cert, tell nginx to reload its config now.
This causes the cron job to run only when a Zulip-managed certbot
install is actually set up.
Inside `install`, zulip.conf doesn't yet exist when we run
setup-certbot, so we write the setting later. But we also give
setup-certbot the ability to write the setting itself, so that we
can recommend it in instructions for adopting certbot in an
existing Zulip installation.
This helps make this script suitable to run on existing installations,
by mitigating any worry about clobbering existing certs with links to
the new ones, in case the admin changes their mind or was using the
certs for something else too.
If we were making an old-fashioned webroot where hand-written static
HTML files went, somewhere under `/srv` would be most appropriate.
Here, this webroot is really more of an implementation detail of the
certbot set up by the Zulip installer/packaging, containing transient
state. So someplace under `/var` is appropriate, and specifically
under `/var/lib/zulip` in order to properly namespace it.

This fixes a regression in ae5ba7f4fd,
where Zulip would 500 if the newly added system bots didn't exist on
the server.
This also fixes a moderate size performance problem where we'd fetch 5
users from memcached or the database in a loop.
Note from tabbott: While this initial version is experimental and
definitely incomplete, we expect to have a solid version done over the
next few weeks (after more refactoring). We're merging this now to
make it easy to test both versions when refactoring our CSS.
Fixes#267.
This fixes a regression in 25c669df52.
We were draining the queue in both the superclass and the subclass,
so by the time the subclass started processing events, there were
no events to process. Now the subclass properly uses the events
passed in from the superclass.
