Cleaning up settings name, Stats URL and redacting node details (#35)

1. Renames the settings to have opendistro.asynchronous_search 2. Replaces _stats to stats 3. Redacts the extra private details exposed by the stats 4. Corrects throttling messages Co-authored-by: Bukhtawar Khan <[email protected]>

 **Tunable Settings**
-1. `opendistro_asynchronous_search.max_search_running_time` : Maximum running time for the search beyond which the search would be terminated
-2. `opendistro_asynchronous_search.max_running_searches` : Concurrent searches running per coordinator node
-3. `opendistro_asynchronous_search.max_keep_alive` : Maximum keep alive for search which dictates how long the search is allowed to be present in the cluster
-4. `opendistro_asynchronous_search.max_wait_for_completion_timeout` : Maximum keep on completion to block for the search response
