melanie witt 6bed39cd6e Add config option for neutron client retries
Nova can occasionally fail to carry out server actions which require
calls to neutron API if haproxy happens to close a connection after
idle time if an incoming request attempts to re-use the connection
while it is being torn down.

In order to be more resilient to this scenario, we can add a config
option for neutron client to retry requests, similar to our existing
CONF.cinder.http_retries and CONF.glance.num_retries options.

Because we create our neutron client [1] using a keystoneauth1 session
[2], we can set the 'connect_retries' keyword argument to let
keystoneauth1 handle connection retries.

Closes-Bug: #1866937
