Create ircbot container

This container installs Limnoria, the supybot replacement as the
generic ircbot container.  We install meetbot plugin as a sibling
project.

Previously we've conflated supybot with meetbot, which is a bit
confusing because meetbot is a plugin, but we also use other plugins
such as the channel logger.  We also hope to convert some of our other
bots to Limnoria (ptgbot?) to consolidate everything.  For this reason
I've called this the more generic "ircbot".  The image installs
meetbot as a sibling project, with the idea being any other plugins
would also be installed as siblings.

The siblings install expects the work directory to be a relative
directory.  I'm not sure we run this from other projects, but this
will work the same if we do.

Depends-On: https://review.opendev.org/c/opendev/meetbot/+/793876
