The Modularity tests rely on an external script to test the modular
behaviour of DNF. There is a potentional risk that the connection
is be down and the script cannot be downloaded.
This enhancement uses a regular OpenQA perl test case script to only
invoke DNF commands and parse their output to test the same behaviour
that we have been testing already.
This enhancement picks a random module for each of the operations,
and thus tries to mimick reality a little bit more.
