scan_packages: made adding package managers easier (#49079)
* made adding package managers easier added portage support * moar pkg mgrs and moar info - added 'pkg' pkg manager (freebsd) - added pip - more apt info * updated clgo * Updates from feedback Co-Authored-By: bcoca <bcoca@users.noreply.github.com> * incorporated more feedback and added docstrings * moar from feedback - made manager list dynamic and names based on class - better not found msg - made abstract metaclass again - test is now init exception - module to global - better dedupe comments * more targetted errors/warnings * added strategy, reordered to conserve priority * rpm > apt * move break to top * fix trate * piping it * lines and meta * refactored common functions - moved pip into it's own module - cleaned up base clases - ensure 'lower' match in package_facts * missing license * avoid facts * update clog * addressed feedback * fix clog * cleanup * upd * removed pip as that was removed * renamed cpan * added a single line since 2 lines are needed to be readabnle instead of just 1 line, it is a huge problem otherwise * fix internal ref * not intended in this round * updated as per fb

C(first) means it will return only informatino for the first supported package manager available.

C(all) will return information for all supported and available package managers on the system.
