Public bug reported:

Discovered downstream [1] that the [neutron]http_retries config option
has no effect on calls to the port binding API, so calls to it are not
resilient like our other calls to the neutron API.

The neutronclient didn't have support for the port binding API at the
time when nova needed to call it, so a manual ksa client was created in
the interim.

When the [neutron]http_retries config option was added [2], this manual
client was missed and thus never does any retries.

The backportable fix for this will pass the CONF.neutron.http_retries
option to the ksa client and the following proposed change to use the
now existing neutronclient support should be reviewed and merged to
prevent future similar bugs:
