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).

Fixes: #17
