Adds delete of extra-dhcp-opt to the client

Add support to delete existing extra-dhcp-opt(s) for a port
via the port-update operation. To use it, set the opt_value=null
of the opt_name that you want deleted (i.e. neutron port-update
--extra-dhcp-opt opt_name=tftp-server,opt_value=null), which will
delete this DHCP option from the port.

Print human friendly string as an error message

This commit also removes a blank line displayed
when error_dict['detail'] is empty.

When 403 is returned, Forbidden exception is raised from
HTTPClient (neutronclient/client.py). There is no reason
this exception is raised by it. By this commit v2_0.client
now handles 403 response to show human friendly message
by parsing Neutron 2.0 -specific error format.

Supporting Net-Partition as extension for Nuage plugin

A net-partition provides administrative separation between groups of tenant
routers/networks/subnets. Within a net-partition, subnets can be shared, and
VMs can connect multiple vNICs to subnets within the net-partition.
For security and isolation between organizations, VMs may not connect
VNICs to subnets within more than one net-partition.

This work is in accordance with bp/nuage-networks-plugin which is
under review: https://review.openstack.org/#/c/67272/

New exception when auth_url is not specified

Certain scenarios into the neutron client will not specify the
auth_url.  This is typically when a token is specified.  However, when
the token is expired the neutron client will attempt to refresh the
token.  Users of this may not have passed in all of the required
information for this reauthentication to properly occur.

This code fixes an error that occurs in this flow where the auth_url
(which is None) is appended to another string.  This results in a core
Python error.

The update will provide a more targetted error message specifying to
the user that the auth_url needs to be specified.  An associated unit
test is also included to validate this behavior.
