melanie witt 11daac03bf 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.
