enable RDMA testing for Brew
This patch adds capability to test Brew builds with RDMA changes. Such a build has to have "rdma" suffix.
The patch does following changes:
- use kpet's print-test-cases to see if any tests are generated for any given test set and patches
- don't hardcode strings, beaker_rdma.xml -> ${RDMA_TEMPLATE}
The check to exclude rdma set in normal job has been merged some time ago. This patch should be followed-up by patch to kpet-db to allow generating rdma tests for baselines.
