Release bgpcep

Do not use ListeningExecutorService

We ignore return from submit() -- hence we can just use execute()
instead. Also drop a FIXME to terminate the ExecutorService, as it seems
to be just hanging.

Consolidate feature repositories

We should only have features-bgpcep, not a separate repository for each
set of features. This squashes the definition and separates
odl-bgpcep-bgp-benchmark into features-bgpcep-testing.
