The integration tests will now read the manifests from the same source
that is used in the examples for installation. No longer is there a need
for a copy of the CRDs in the integration test code.
The tests will read the manifests directly from disk under a path
relative to the rook root. The upgrade test will read the manifests from
a github url where the base version has been published.
