Revise RMR install scripts for deb/rpm

Use -nv (non verbose) instead of -q (quiet) in wget.  Error messages
are suppressed with -q which makes failures totally inscrutable.

Default PackageCloud repository to release, but extend query for repo
tag in rmr-version.yaml file to allow use of staging repository.
