    Do not use config subscription in couch_index

    The simple fact that we call config:subscribe_for_changes causes the hike in memory consumed by couch_index process. Monitoring the changes for "query_server_config.commit_freq" is not worth it. We would just call config:get_index when we need to.

> In spite numerous attempts to improve memory consumption of config listener. The simple fact that we call config:subscribe_for_changes causes the hike in memory consumed by couch_index process. Monitoring the changes for "query_server_config.commit_freq" is not worth it. We would just call config:get_index when we need to.
