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.
