[EXPERIMENTAL] Integration Test on Swarm

This commit adds contrib/integration-cli-on-swarm/integration-cli-on-swarm.sh,
which enables IT to be running in parallel, using Swarm-mode and Funker.

Please refer to contrib/integration-cli-on-swarm/README.md

The test takes almost 5 to 6 minutes, with 10 n1-standard-4 GCE instances.
