Updated git submodules

Project: integration master 6b7b3a1880ca51f258ccc004d92b60ce13b4a014

Increase Wind River k8s VM instance size

Also revert integration-override.yaml back to
full ONAP deployment.
Add a new integration-override-minimal.yaml
for the reduced deployment.

The ability to easily specify the desired
helm override file will be addressed in a later
patch.
