      In order to aid in removal of featureCompatibilityVersion-3.4 dependent behavior, the featureCompatibilityVersion parameter should default to 3.6 instead of 3.4. The "unset" semantics should be preserved. shardsvr nodes should also create a featureCompatibilityVersion document with version equal to 3.6 on clean startup. The special handling to create admin.system.version without a UUID for shardsvr nodes should be removed.
