Implement support for recent versions RabbitMQ

[davidalger]

The versions of Erlang available via Epel and default Debian/Ubuntu repositories do not satisfy the precise requirements RabbitMQ has for Erlang dependencies.

This PR accomplishes the following:

• Updates installation on EL to install pinned Erlang version from the RabbitMQ PackageCloud RPMs
• Updates installation on Debian/Ubuntu to install pinned Erlang version from the RabbitMQ Bintray repositories.
• Removes dependency on repo-epel role.
• Updates the default pinned RabbitMQ version to 3.8.5 (latest at time of this PR)
• Locks Erlang version to 23.0.2 (latest fully compatible with 3.8.5 at time of this PR)

Additional side-note: This is similar to PR #4 although more complete as #4 does not cover updates required to support non-EL distros and did not support locking the Erlang version as this does. Thanks to @claudineimatos for the inspiration. Been using the method on this PR (derived from his, but not the same) for a while for a few EL installations, but just now made the time to pkg it up and add support for Debian/Ubuntu allowing CI builds to pass.
