RHEV compute resource without quota fails on creating a vm with "Failed to create a compute" "Internal Engine Error"
Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1123685
Steps to Reproduce:
1. create compute resource on rhev with a blank quota
2. provision a host on that compute resource
Provisioning fails with "Failed to create a compute" "Internal Engine Error"
Additional debugging pointed to the quota parameter not being accepted, when set to "", switching to nil seemed to fix the issue
