Subject: [PATCH] puppet: Prevent unattended upgrades of erlang-base.

When upgraded, the `erlang-base` package automatically stops all
services which depend on the Erlang runtime; for Zulip, this is the
`rabbitmq-server` service.  This results in an unexpected outage of
Zulip.

Block unattended upgrades of the `erlang-base` package.
