[python-fuelclient] fuelclient doesn't support delete deployment graph operation, i.e. 'fuel2 graph delete' command is not implemented

[Vitalii Kulanov]

Detailed bug description:
python-fuelclient doesn't implement delete deployment graph operation (http://docs.openstack.org/developer/fuel-docs/userdocs/fuel-user-guide/cli/cli_graphs.html):

[root@fuel ~]# fuel2 graph
download execute list upload

However Nailgun supports it https://github.com/openstack/fuel-web/blob/master/nailgun/nailgun/api/v1/handlers/deployment_graph.py#L146-L167

So 'fuel2 graph delete' command has to be implemented in order to allow user to remove deployment graphs.

Reproducibility:
Always

Description of the environment:
[root@fuel ~]# shotgun2 short-report
cat /etc/fuel_build_id:
 667
cat /etc/fuel_build_number:
 667
cat /etc/fuel_release:
 10.0
cat /etc/fuel_openstack_version:
 newton-10.0
