[RFE] Ability to match on return types with "anything but"

[jmle]

In this story we would need to match against specifically annotated method declarations that also do not return a certain type. Currently, and according to the Eclipse JDT docs, we can only look for methods that return certain types, with a query like *(*) [type], but that type cannot be negated.

We could potentially achieve this in the adapter layer of the Java provider, in a post-processing step.

Implement konveyor/rulesets#141 after this is completed.
