swarm/src: Remove ConnectionHandler (#2519)

Browse Source 
The `ConnectionHandler` trait is not exposed to users. The only
implementor of `ConnectionHandler` is `NodeHandlerWrapper`. Thus
`ConnectionHandler` is a superfluous abstraction. This commit removes
`ConnectionHandler`.

Next to this large change, this commit removes the `Tmuxer` trait
parameter. `Swarm` enforces dynamic dispatching via `StreamMuxerBox`
anyways, thus the trait parameter is useless.

As a follow up to this commit one could rename `ProtocolsHandler` to
`ConnectionHandler` and `NodeHandlerWrapper` to
`ConnectionHandlerWrapper` or just `Wrapper`.
