RPMs matching re-implemented [RHELDST-6392]

This rather bigger change moves matching non-modular binary,
debug and source packages to separate class.

This change provides 1:1 functionality as previous code, but is more
robust, reliable and uses better paralellizition and should be also
a bit faster than the previous implementation.

I also removed some unused code, added and improved tests, added
some custom config to pylint in order to pass static checks.
