Description

In 3.6 the Oplog Resize procedure was changed from "standalone-drop-recreate" to the replSetResizeOplog command. However, this command only works for the WiredTiger storage engine, and will fail if attempted on an MMAPv1 replica set member. This is only a problem in the 3.6 and 4.0 docs, because MMAPv1 support is being removed in 4.2.

Scope of changes

Update replSetOplogResize + oplog resize pages to point to the 3.4 resize oplog instructions for users on MMAPv1, call out upcoming MMAPv1 deprecation and guide to rolling to WT.
