* Produce 2 binaries instead of one
This generates a different binary for the register command as to not
bundle it with the full operator.
On the makefile separated builds have been done for operator and
registry.
On the docker image a different container is created for the register
and pushed to a different repo as well.
For releases gorelease generates 2 different binaries.
