To Reproduce Steps to reproduce the behavior:
In RHOSO environment with huge number of compute nodes run "openstack hypervisor list" command. It could take more that 40 seconds to complete and provide an output.

Expected behavior
Command is completed quickly by default, extra delays are expected when operator explicitly asks for extra data.

Bug impact
May block command from completion with default timeouts (it will fail before because HAProxy will return 504). Also, we shouldn't likely activate time-consuming options by default.

Known workaround
Specify earlier API version (2.68 for example)
