Some basic stuff
Added setup for the other providers, might need refactoring then
Added correct sys_type translation, added register_event to all relevant tests in the file
Event integration with power control working, now it needs a bit of refactoring to be fully acceptable
Grouping with the test names
Use utils.providers instead of hard-coded list
Moved the fixture for register_event out of the class
Fixed comments in events.py, added skipping for import_policies
