Timing out in nova-api requests to neutron

[Arx Cruz]

On low memory usage environment nova-api is timing out when make requests to neutron, because the default 30 seconds isn't enough to neutron send the response.

[John Trowbridge (trown)]

added newton backport potential as this is environment is mainly for CI and developer environments so backport is very low risk.

    Increasing neutron timeout for low memory usage

    We are noticing several tests failing in our low memory environment
    because of timeout in neutron requests.
    As an example the test
    tempest.api.compute.servers.test_server_actions.ServerActionsTestJSON
    fails because it requests to plug a vif, and send request to neutron,
    which responds in more than neutron_url_timeout, and since the option
    vif_plugging_is_fatal is set to True as default, the test fails.
    Shortly thereafter, checking in neutron log you can see the request,
    returning with the proper status, after more than neutron_url_timeout,
    however, it's already too late once nova already marked the instance
    with error status, and so the test fails.

    Closes-Bug: #1641135
