PHPUnit Command: Support more native command options

[joaop221]

Hi there!

Moodle plugin CI supports a little bit of parameters specified by PHPUnit 9.x documentation.

My suggestion is to adapt the command to receive, at least, more coverage and log reporting options.

This can be done, by changing the ideia of only proxy params to create some logic. For instance:

moodle-plugin-ci phpunit --fail-on [ warning, incomplete... ] --log [ junit, teamcity... ] --coverage [ clover, text... ]

If these ideas are viable for this project, I'm at your disposal.
