Subject: [PATCH] Add tests for whether mixin output is checked-in

With the proposed workflow mixin output is generated offline and
checked into version control for direct usage.
A test is added to check whether the generated rules and dashboards
match the checked-in version.
Additionally checks for the shellscript generating the mixins and for
the mixin test playbook from above are added.
