https://github.com/projectcalico/calico/ has moved to https://github.com/projectcalico/felix/. This change updates the calico_git_repo variable accordingly. The role SHA for os_neutron is updated as the updated SHA includes the same fix. Without it the repo build process tries to access both repositories.
