Operator install manifest

[sync-by-unito]

create a manifest in the operator repo that can install the operator via kubectl, so something like this will work:

curl github.com/gresearch/armada-operator/config/samples/deploy_operator.yaml | kubectl apply -f -

this is basically the same as "make install" but it will reference a dockerhub image for the operator and won't require cloning repo, running make commands, etc.
