migration: Add qtest for migration over RDMA

This qtest requires there is a RDMA(RoCE) link in the host.
In order to make the test work smoothly, introduce a
scripts/rdma-migration-helper.sh to detect existing RoCE link before
running the test.

Test will be skipped if there is no available RoCE link.
# Start of rdma tests
# Running /x86_64/migration/precopy/rdma/plain

# To enable the test:
# Run 'scripts/rdma-migration-helper.sh setup' with root to setup a new rdma/rxe link and rerun the test
# Optional: run 'scripts/rdma-migration-helper.sh clean' to revert the 'setup'
