Suggestion for change to kustomize setup

[mikenairn]

Rename everything in config/policy-controller to be consistent with normal kubebuilder/operatorsdk controller naming conventions.

Update the default mgc overlay to allow specifying a different nameprefix for mgc (gateway) and policy components.
