Michael Gugino 0736336a71 Implement network agents functionality
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>

Change-Id: I83ede6f89c37e7bdc38d7e9e7bb9d80e94c8becc
Implements: blueprint implement-network-agents
Depends-On: I9755637f76787d5fac8ff295ae273b308fcb98d0
