[policies] add SuSE policy

Add a basic policy class for SuSE distributions and implement a
simple OpenSuSE policy (currently this will work with any SuSE
release).

A new SuSEPlugin tagging class is introduced for SuSE-specific
plugin cases. The policy currently also allows the RedHatPlugin
tagging class to run: this quickly enables a large number of
plugins for the distribution but will require manual testing
to identify cases where a dedicated SuSEPlugin must be created.

Fixes #523.
