Migrate existing rules to PSSA2 #1485
Description
PSSA2 should support most or all existing PSSA rules. Some rules may be inappropriate for continued use and others may need to be expanded, but gradual migration of rules should be possible.
Dependencies on Helper methods should be replaced with general purpose implementations that live under the appropriate class and injected into rules at instantiation time.
Some rules may need refinement or improvement, particularly in name or implementation. When this is done, a mechanism should be provided to improve compatibility.
