 Description   

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.

Message: SERVER-32741 Remove erroneous TODOs

The uuid field is intentionally optional in CollectionOptions because
CollectionOptions is used for both parsing stored collection options and
parsing user-specified collection options, and users are not allowed to
define their own UUIDs.
