* Add module support for wrapper script calls The scripts poller.php and discovery.php offer a module option (-m), which may be used to specify specific modules for polling/discovery, possibly for special (and then faster) testing or for example rediscovering the fdb table (on all hosts). Until now, this was not possible with the python wrapper scripts. Now they support a '-m' option, where comma separated module names may be passed. This will currently only work with poller and discovery, though. * Replace single quotation signs with double ones (empty strings only) * Fix more code lines (quotation signs, indentation) Also 'reduced' if-else-clause size at end of LibreNMS/wrapper.py (do not call method at each branch, instead prepare a value for modules) * Add commas after last parameter of dict+methode Also an additional comment sign before # * Fix two leftover single quot. signs … * doc: Add documentation for module support
