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

Partial-Bug: #1610883

python-neutronclient implements the following command set:

agent-list, agent-show, agent-delete

These commands display and modify various network agents and their
information.

python-openstacksdk has supported the api calls for these commands,
but python-openstackclient does not implement these commands.

This commit adds support for the following commands:

openstack network agent list
openstack network agent show <agent>
openstack network agent delete <agent>

According to the code in SDK:
https://github.com/openstack/python-openstacksdk/blob/master/openstack/network/v2/rbac_policy.py#L34
we can see the conlumn of "target_tenant" should be
"targer_project_id" but not "target_project". It is
the reason why could not show the "target_project"
in OSC, so this patch fix it.

Closes-Bug: #1608903

Add "network rbac set" command which just supports
setting a target project.
Also, This patch adds the doc, unit test and functional test.
But there is a bug of showing network RBAC
https://bugs.launchpad.net/python-openstacksdk/+bug/1608903
We need to skip the functional test before this bug fixed.
