Add enable_centos_release parameter

Add an `enable_centos_release` parameter, defaulting to `false`, except
on CentOS, where it defaults to `true. If enabled on any OS in the
RedHat family when `repos_ensure` is also disabled, it controls adding
the `centos-release-rabbitmq` package (currently
`centos-release-rabbitmq-38`)

Fixes voxpupuli#1033
Closes voxpupuli#1032
