Disable puppet runs on eavesdrop

As noted inline, we want to merge Python 3 fixes to meetbot master and
don't want the production server to try installing it any more.
eavesdrop01.opendev.org will be the replacement.

Changes to install Limnoria/meetbot and perform meeting and channel
logging on eavesdrop01.opendev.org follow.  This will leave ptgbot as
the last service running in-situ on eavesdrop01.  This should be moved
to the opendev server when it is updated to move to OFTC.
