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.

KeyError cause the command "module list --all" failed,
fix it, and do refactor to filter private modules and
reduce the loop times, add related unit tests and
functional tests.

this will better isolate the unit tests from the functional tests.
unfortunately, the "integration" tests had to be lumped into the
"unit" tests since we need the separation in testr.conf
