This adds a script that checks for common whitespace issues
(per our house style) and can (if run with --write) correct some
of them. It adds a run of the script (without --write) to the
tox config, and includes fixes for all the issues the script
discovered in the existing tests and libs.

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.
