Right now the refreshTotalCount() function in QueryAnalysisSampler does not take into account an embedded mongos and as a result will give an incorrect count.

The function needs to be updated so that it satisfies the following criteria (this is from Chou):

1. On a mongod in a standalone replica set, we want to count the update, delete, findAndModify, find, aggregate, count, distinct commands that it executes.
2. On a mongos, we want to count the update, delete, findAndModify, find, aggregate, count, distinct commands that it routes.
3. On a shardsvr mongod without router role, we want to count the nested aggregate commands (i.e. $lookup,$graphLookup and $unionWith) that it routes.
4. [New] On a shardsvr mongod with router role, we want to count the nested aggregate commands AND the update, delete, findAndModify, find, aggregate, count, distinct commands it routes (**).

(**) is not possible yet because the globalOpCounters count both commands that a mongod receives on the shard port and on the router port. As a result this ticket will also depend SERVER-79353 being completed.
