* 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
