Merge inject_* paired methods

[divagant-martian]

Addresses #2434

• Include the number of other reported connections in inject_connection_established
• remove inject_connected
• Include the number of remaining reported open connections in inject_connection_closed
• remove inject_disconnected

I'll leave the changelogs for later to avoid cluttering the diff for review.
In an attempt to not interfere with the logic of the protocols I left (for now) a TODO note in the autonat behaviour regarding a mapping that seems to never be cleared

Thanks for looking into this! 🙏

@divagant-martian Could you please point out to me what line/ mapping in the autonat behaviour you are referring to?

I think @divagant-martian mixed up libp2p-autonat and libp2p-relay. I think the comment refers to #2445 (comment).

Looks good to me overall apart from changelog entries and version bumps. Given the recent release (v0.42.0 and v0.42.1) let me know if you need help with the various semver version updates.

Hey @mxinden can you share your upgrade version tools?

Hey @mxinden can you share your upgrade version tools?

Version upgrades have been done via #2469, thus only the normal changelog entries are needed here.

(The version tool is a VERY hacky Python script written by a total Python novice (me). I am not sure it is yet ready to be seen by other human beings :D )

[divagant-martian]

Grand, I'll add the Changelog entries!

[mxinden]

Thanks. Can you add an entry for swarm/CHANGELOG.md as well?

[divagant-martian]

done! Ty @mxinden

[mxinden]

Merge needs to incorporate #2076 which is still using the old methods. Could you incorporate that @divagant-martian? Sorry for the trouble.

[divagant-martian]

@mxinden dcutr does not have a CHANGELOG, how would it look like for a first time?

[mxinden]

Oh, my bad. I am not a good rust-libp2p citizen. No need to add an entry for libp2p-dcutr here, given that it has never been released. I will add a changelog in a separate pull request. Thanks for raising it.

[mxinden]

Thanks for the clean up!
