It looks like you're using the wrong miniprotocol number here when running over NodeToClient.

There is a -c option for specifying how many keepAlive messages should be sent.
After that cardano-ping sends keepAliveDone and shuts down the connection cleanly.
You should implement that logic here.

Even though it's not implemented using `cardano-diffusion`, we often need to release it together with `cardano-diffusion`.
The instantiation of `ChainSync` is polymorphic enough to support both protocols.
We used to need to call `cborTermVersionDataCodec` to get `VersionDataCodec` from `CodecCBORTerm`. The `VersionDataCodec` and `cborTermVersionDataCodec` is moved to `ouroboros-network:api` library (`Ouroboros.network.CodecCBORTerm` module). `cardano-diffusion` provides both `nodeToNodeVersionDataCodec` and `nodeToClientVersionDataCodec`. This required a refactorisation in tests to get rid of some newtype wrappers, however the semantics of all the tests is preserved.
The tests started to fail due to usage of version data codec which doesn't satisfy round robin property on invalid version data in the previous commit.
Exposed `nodeTo{Node,Client}VersionDataCodec` instead.

Description
Rationale
This PR re-implements the ping command using
cardano-diffusionand moves itto
cardano-diffusionpackage aspingsublibrary. The library will notrequire changes when new node-to-{node,client} protocol versions are added, and
as a part of
cardano-diffusionit will be always released in lock withcardano-diffusionandouroboros-network. This should make it easier tomaintain it.
Requires: #5200
