Without this patch, openstackclient has no way to specify to which
project a network belongs upon creation. Instead, it uses the project
ID that the user is authenticating with to fill the tenant_id column.
This is a problem because an admin user is unable to specify a project
for a non-admin network. To fix this and to improve feature parity with
the neutron client, this patch adds project and domain parameters to
the network create command and uses the given project name to look up
the project ID.

Neutron does not allow the project to be changed after creation, so no
such parameter has been added to the neutron set command.

Neutron calls the field 'tenant_id', but this change exposes the
parameter as '--project' to support the newer terminology.

If no project is specified, the client defaults to the previous
behavior of using the auth project.

api.network.APIv2 starts with network_list() support to flush out
the skeleton of the Network API.

list_dhcp_agent() supports the --dhcp option of 'network list'

python-openstack client is now using sessions to create clients. This
patch implements creating Network client using sessions.

Anything that needs a service catalog can get it directly from
auth_ref.service_catalog, no need to carry the extra attribute.

ClientManager.get_endpoint_for_service_type() reamins the proper
method to get an endpoint for clients that still need one directly.

Clients that can use ksc Session don't need the old junk to
fake auth anymore:
* compute
* volume

Clients that still need to be fed credentials can pick directly
from the auth object in clientmanager.  The _token attribute is
removed, the token can be retrieved from the auth object:

  openstackclient/tests/common/test_clientmanager.py

This change will break any plugin that relies on getting a token
from instance._token. They should be updated to use the above, or
preferable, to use keystoneclient.session.Session to create its
HTTP interface object.

In a cloud with AZs, you can get multiple entries back from the service
catalog - one for each AZ and then one that is AZ agnostic that's tied
to the region. If the region_name is plumbed all the way through, this
works as intended.
