Formatter rules list is hard-coded

[travisclagrone]

This is technical debt.

The formatter has a list of hard-coded rules, and it can only execute those. It should be refactored to enable the run-time specification of rules via settings. However, more research is needed to determine is there is a necessary reason the rules are hard-coded. See #1277 (comment) and #1277 (comment) for more details.

Yes, thanks.
Just to make it clear: Although hard-coding is not nice, the bigger problem is that that somehow Invoke-Formatter can only choose from those rules. The biggest improvement would be if someone specifies settings, they are actually applied and the hard coded list would only be left for the purpose of defaults.
