Module tests update: per module output, only store modules data that are run (#8355)

* Test data: don't save data for modules that were not run

* Sometimes mibs are prefixed with +

* Save output for each module and only output the errored module.
Also makes it easier to identify modules that were ran.

* Clean up json files.
Message when no module data exists.

* verbose output when phpunit --debug is used
order by for ports
avoid graphite output in tests
only load module_tables.yaml once

* use explode and strpos instead of regex since it is failing...

* Fix some warnings

* Fix whitespace
