Add an operator Helm chart

The submariner-operator Helm chart deploys Submariner using the Submariner operator: it deploys the CRDs, roles, and SAs required to run the operator and Submariner, then pushes a Submariner CR to instruct the operator to deploy Submariner. This patch also adds a Makefile to validate the deployments; run make deploy to test the Helm charts (this will bring up two clusters, install the broker on one of them and the operator on both, and end with a connectivity test).
