Right now, the stats API only provides refresh metrics regarding internal refreshes. This isn't very useful and somewhat misleading for cluster administrators since the internal refreshes are not indicative of documents being available for search. In this PR I added a new metric for collecting external refreshes as they occur and exposing them through the stats API. Now, calling an endpoint for stats will yield external refresh metrics as well. Relates elastic#36712
