Fix beaker task

In puppetlabs_spec_helper 4.x the beaker task was removed. This loads it
from voxpupuli-aceptance. puppetlabs_spec_helper is added for spec_prep.

Support Puppet 7

Forcing the locale in acceptance tests isn't pretty but for now it's a
valid workaround. Note that the candlepin DB is already forced to
en_US.UTF-8 but this affects initdb. We may see similar problems in
production, but in general LANG should be matching a system locale.

Rename outputs in CI and label tests

Update Github Actions workflow

This applies the lessons learned while applying this to Voxpupuli and
The Foreman orgs.

Set cron schedule to daily instead of hourly

Assign more groups in Gemfile

This allows installing fewer gems for specific tests.

Switch to GH Actions from Travis

Add Github action placeholders

These files need to exist for a Github action to trigger on a PR. The
goal of this commit is to have proper CI checks on the actual PR to
switch over.
