All in one makefile rule to build the index and bundle images, push them to a registry and deploy

[fedepaol]

In order to be able to deploy on real clusters using OLM (which provides a more accurate result of what deploying from operator hub looks like) it'd be nice to have a makefile rule that, while setting the proper env variables:

• builds the index image
• uploads it to a registry
• create the proper subscription and all the other resources required to deploy via OLM

We do have something similar with deploy-with-olm but it is tied to the kind deployment.

It would also be useful to be able to optionally replace the bundle dockerfile
