Backport upstream strimzi container sources[1] to amq streams image repo[2]. This consists of

1. Converting Dockerfiles[3] to image descriptor files[4]
2. Copying image shell scripts[5] to module script directories[6]
3. Modifying cekit module install scripts accordingly[7]
4. Fetch MD5s for strimzi/kafka zips from brew, update image descriptor files accordingly

This release is coming with the Kafka bridge as Tech Preview so we have to do the same for the bridge as well [8].
