Change $repos_ensure to default to false.

The problem with it being true by default is that the majority of production
environments, and any in an isolated nextwork, will not want to get the gpg key,
especially if they have not explicitly configured the module to get the rpm from
the rabbitmq repos.  Having the gpg key pulled in by default while installing
the rpm from distro repos seems inconsistent at best, and at worst, causes an
additional fail point for deployments that are unable to contact this location.
Leaving it true by default forces the majority of production users to have to
override this setting.
