Honor [neutron]http_retries in the manual client

Change Ifb3afb13aff7e103c2e80ade817d0e63b624604a added a nova side
config option for specifying neutron client retries that maps to the
ksa connect_retries config option to provide parity with the cinder and
glance clients that have nova side config options.

That change missed passing CONF.neutron.http_retries to the manual
client used for calling the port binding API. This sets the
connect_retries attribute on the manual ksa client so http_retries
will be honored.
