Add targets to Makefile

This commit adds two additional Makefile targets to Makefile:

cleanup: Since operator-controller is the single point of entry and `make run` installs
	 Rukpak and Cert-manager, it would be good to have a target that cleans up the
	 cluster of controller and all its dependencies.

run-local: To be able to run the controller locally, it is useful for developments so that
	   we need not always have to build image to test operator.
