Investigate if this could be used for testing permission based authorization

[juhasipo]

Currently MUTR only properly supports testing role based authorization. Permission based authorization can be tested on some level with role aliases where one role alias is mapped to a certain set of permissions.

Idea 1

• Give MUTR all different permissions
• Define different permission sets in with blocks. Check against all permission sets defined.
• Run with all permission permutations

The problem with this approach is that the permutation count rapidly increases when a new permission is added
