Upstream has notified us[1] about the immediate deprecation and removal
of the PackageCloud repositories we are using. Thus, we must move to the
CloudSmith repos already being used for the erlang dependency for
RabbitMQ.

Closes-Bug: 2021410
Change-Id: I361757b8f76a6c2d087989a36d8f7543aba69e16

Due to decision made during PTG, we're switching back source for
RabbitMQ to packagcloud, since cloudsmith does rotate versions
too aggressively and we can't keep up with them.
With that we're leaving erlang source to be cloudsmith, since
there're simply no other good sources for Ubuntu/Debian.

Switch to using cloudsmith repo as a source for rabbitmq and erlang.
This allows us to be consistent about repository that is
used across supported distributions along with switching from
unreliable erlang-solutions that tend to fail periodically.

We make remote network hits to get the GPG keys which are quite
unreliable, and apt_key does not support using a proxy properly [1]
so let's store them inside the role and use them.
The implementation here matches that which was done in the
galera_client role in I520ccbadf3320b0d07fc83e3dbec9ea2bd16ec83
