Do not force unit tests to be run while the rook repo is in the GOPATH. Now that Rook uses go modules, this is no longer necessary. Allow this by creating a helper function that unit tests can use that return the on-host path to the `rook` project root. Signed-off-by: Blaine Gardner <blaine.gardner@redhat.com>
