melanie witt 71971c2062 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

Operators

To learn how to deploy and configure OpenStack Nova, consult the documentation available online at:

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:

Developers

For information on how to contribute to Nova, please see the contents of the CONTRIBUTING.rst.

Any new code must follow the development guidelines detailed in the HACKING.rst file, and pass all unit tests.
