As noted in the commit message; a new config option has been introduced.
Moving this to the manual team so they can consume.
Note this is for master and there are separate bugs for other branches.

Title:
New option for num_threads for state change server
Status in openstack-manuals:
New
Bug description:
https://review.openstack.org/317616
Dear bug triager. This bug was created since a commit was marked with
DOCIMPACT.
Your project "openstack/neutron" is set up so that we directly report the
documentation bugs against it. If this needs changing, the docimpact-group
option needs to be added for the project. You can ask the OpenStack infra team
(#openstack-infra on freenode) for help if you need to.

New option for num_threads for state change server
Currently max number of client connections(i.e greenlets spawned at
a time) opened at any time by the WSGI server is set to 100 with
wsgi_default_pool_size[1].
This configuration may be fine for neutron api server. But with
wsgi_default_pool_size(=100) requests, state change server
is creating heavy cpu load on agent.
So this server(which run on agents) need lesser value i.e
can be configured to half the number of cpu on agent
We use "ha_keepalived_state_change_server_threads" config option
to configure number of threads in state change server instead of
wsgi_default_pool_size.

DocImpact: Add new config option -
ha_keepalived_state_change_server_threads, to configure number
of threads in state change server.
