Subject: [PATCH] Add watcher target to deploy operator via olm

This pr adds two targets:
* `make watcher`: It generates olm.yaml file and installs the
  watcher-operator using oc.
* `make watcher_cleanup`: It generates the olm.yaml file and undeploy
  the watcher-operator using oc.
* `make watcher_deploy`: To deploy the watcher service
* `make watcher_deploy_cleanup`: To undeploy the watcher service

It also provides $CATALOG_IMAGE var to pass custom watcher-operator
index image.
