[OchiengEd]

Create a an operator-controller migration prep branch. Fetch and merge the contents of the catalogd migration prep branch being keen to preserve the git history

We expect a merge conflict that would affect the go.mod, go.sum and .gitignore. You can accept the versions of these files in the operator-controller repository.

Update import paths to point to the operator-controller repository.
