python-openstacksdk does not match its pip name which is openstacksdk.
So setting python-openstacksdk in LIBS_FROM_GIT leads to devstack
thinking there is a problem.
Put in a workaround for now. It would be better to either:
a) rename python-openstacksdk repo to openstacksdk
b) rename the pip name for openstacksdk back to python-openstacksdk
c) add general support in the various GIT hashes for a pip name
