Proposal: make version mandatory in API URLs

[thaJeztah]

Just a quick placeholder, following a discussion on Slack;

Currently we accept both /something ("latest" API version), and /vXX.YY/something (API version "XX.YY").

The "latest" API version can be troublesome, because software using the "latest" version (and not explicitly defining a version), can break after an upgrade of the daemon.

Instead, we can deprecated the "latest" URLs, and require consumers of the API to explicitly specify the API version they're using.

Thanks @thaJeztah! While I believe that this might make our lives easier, I'm also interested to hear reasons why we may not want to do this.

+1 from me.

I already have a branch where I've tried this out, and surprisingly it only breaks a few tests. I could fix up the tests and push the branch somewhere, if there's interest.
