  The extension tests were duplicated to have both compute and network
  extensions tests so the nova-net case will still exercise the extension
  commands.

Also clean up formatting from previous reviews to make the Network functional
tests look and act consistently.

We need to skip some functional tests when testing against a nova-net cloud
so add the bits to detect that.

Also JSON-ify the quota functional tests and add the skips for nova-net.

A special scenairo is that users want to check the commands
help message, but don't set authentication info at all. Add
a related functional test case to cover it.

Implement Neutron feature of Quota List into
OpenStack Client.

Partially-Implements: blueprint neutron-client-quota

The output of current "command list" is so long, it's
very difficult for users to find out the commands
they care about.

Add "--group <group-keyword>" option to filter the commands by group
name keyword, like: --group volume, list all openstack.volume.v2
(cinder) commands

That support the scenario that users need to know the current support
commands of some OpenStack services(nova, neutron, cinder and so on) in
OSC.

openstacksdk bug/1588823 exist, no good way to add __version__ for
openstack module properly, fix the issue in osc side, make openstacksdk
module information be available.
