Move test cases from drools-compiler to drools-test-coverage/test-compiler-integration so that we can increase the test coverage for executable-model.
At the moment, I'm not yet sure how many of the test cases can be moved. Basically DRL based test only.
> there are some tests in -compiler that are not supported in the model compiler (I'm thinking about all the ASM/type generation related). That should be left in -compiler and hopefully moved outside like the traits
If we find test failures by executable-model, we would spawn new JIRAs to deal with them one-by-one.
NOTE: Most of drools-compiler test cases have been moved to drools-mvel
