Add override timeout for openstack exporter

[alban lecorps]

currently it is impossible to override timeout for openstack exporter.

https://github.com/openstack/kolla-ansible/blob/master/ansible/roles/prometheus/templates/prometheus.yml.j2

currently, timeout is hardcoded with 10s, if you have a big openstack infrastructure it can't take more than 10s to scrape. So the openstack exporter is unasable in that case. I propose to variabilize this setting like we did for prometheus_openstack_exporter_interval.
