 Description   

WIredTiger recently added a new feature to cache WT_CURSOR handles. The option enables caching by default, but MongoDB doesn't need a WiredTiger cursor cache, since it implements one of it's own.

We should disable the WiredTiger cursor cache via a configuration option in MongoDB.

We are still using the MongoDB caching, so no need to double up.
Branch: v3.6
