NOTE: we can not merge this until FR3 branch is created upstream.

Goal: 

When integrating watcher-operator into the top-level openstack-operator, the watcher-operator bundle and deployment will be managed by the openstack-operator.

For that, watcher-operator needs to be added to the openstack-operator-index and the deployment managed by it. See:

https://github.com/openstack-k8s-operators/openstack-operator/commit/a61502c99a9305e31fcf188f3fc15de5a3fa8460

Also we need to sync bindata to get the bundle and define the RELATED_IMAGE_WATCHER_OPERATOR_MANAGER_IMAGE_URL variable.

Acceptance Criteria:

• Watcher-operator is included in the openstack-operator
• watcher bundle is included in openstack-operator
• watcher operator controller manager is deployed by openstack-operator.
