Remove bazel

[mnecas]

• Remove all .bazel files
• Remove .bazelrc
• Add forklift-operator-index dockerfile to build the opm catalog index.
• Fix operator containerfile which was missing the ansible-galaxy requirements
• Add ovirt-populator dockerfile for upstream
• Reflet the makefile changes in the README

Makefile changes:

• Replace the bazel builds with the container builds
• Add deploy-operator-index target to deploy the new index image
• Start to dynamically adapt the bundle images depending on the images which were build before.
• For example you can run

export REGISTRY_ORG=user
make push-controller-image \
     push-operator-bundle-image \
     push-operator-index-image \
     deploy-operator-index

• This will build the controller image and push it to your user in quay.
  Next it will build the bundle image which points controller to the newly built image and the other images will be pointing to the "default" images from kubev2v org. This way we don't need to rebuild all images if we want to test the changes only in one image.

Depends on: kubev2v/forkliftci#136
Which depends on these changes so we need to merge one of them first even with a failing pipeline. I did a test pointing to the test branch and it passed.

As a test I have updated the github action to use my branch from the forkliftci as this patch is depending on it. kubev2v/forkliftci#136

With those changes the action passed
