Added unit tests for redhat_subscription module (#58665)

* Fixed the redhat_subscription module:
  - Option 'pool_ids' works in Python3 now
  - It tries to attach only pools IDs that are available
  - Optimization of code: do not call list --available, when
    no pool is requested
  - Simplified configure() method
  - Small changes to generate same commands on Python2 and Python3.
    Order of arguments/options and pool IDs have to be same to
    be able to run unit test using Python2 and Python3.
  - Added fragments file for redhat_subscribtion module
