Sharding 2017-10-23
Description
This ticket should update the places where we check a client's wire protocol version to
- decide what maxWireVersion to send back in the isMaster handshake (to make the client fail to connect if it's too old)
- decide whether to close client connections from clients that are too old
- decide whether a shard is too old to add to a cluster
particularly to check "in any state other than fully downgraded to 3.4" rather than just checking "in 3.6."
