    VMware: Handle concurrent registrations of the VC extension
    
    During initialization, the Nova compute driver checks whether a
    vCenter extension with key 'org.openstack.compute' exists and if
    not, it registers one. This is a race condition. If multiple
    services try to register the same extension, only one of them
    will succeed. The fix is to catch InvalidArgument fault from
    vSphere API and ignore the exception.
