feat: upgrading sonatype central client

[Andrapyre]

Description

This PR adds the following:

• support for publishing snapshot libraries to Sonatype Central.
• Java 8 compatibility for the sonatype central client
• logging for sonatype central status checks when the deployment hits a different status
• revised status checks which stop after the deployment is validated rather than waiting until the deployment is published

/closes #564

@xerial , a quick PR when you have time. Thanks!

[chitralverma]

@xerial any updates on this PR?

@eed3si9n , would be great to get your review on this. It looks like the Sonatype Central api is down and so it's not possible to run tests against it. All bundle uploads are timing out currently (even with tests that used to succeed). I would prefer to test this manually against it to make sure it works before merging.

I guess anything that's built on JDK 8 would be a progress, but if each pull request takes two months to land, we might as well try to fix the timeout issue in one go?

@eed3si9n should we migrate the repo to sbt organization if @xerial doesn't have the time to look at this?

[eed3si9n]

Yea, if people are ok with it, I can actually start a library and maybe build this feature into sbt itself?

The deadline is soon, so this would probably be the best course of action. Let me know if there is something I can do.

@eed3si9n , I didn't think my initial PR to support sonatype central would ever get merged in this repo, so I started this sbt plugin a little less than a year ago. https://github.com/lumidion/sbt-sonatype-central. At the end of the day, the PR got merged here, so I didn't continue. The plugin just needs a little tinkering (lib updates and java 8 compat testing) and we could copy over the built-ins from sbt-ci-release and it should be enough. Bigger problem at the moment is that the sonatype central api itself seems to be having issues. I used the sonatype central library to upload packages over two weeks ago and it worked with no problem. Last week, the same lib couldn't upload any packages at all and users reported complete inability to upload anything here, as seen in this ticket: lumidion/sonatype-central-client#18.

Potentially some of the reported timeout issue might be resolved if we increased the timeout? See also
lumidion/sonatype-central-client#22. Either way, if you would like to get sbt-sonatype-central into JDK8-compat state, I'd be happy to go with that solution as well.

Thanks for working on it! We're all forced to migrate by the end of June unfortunately, this becomes a very important feature / PR.

Here's a PR to add this to sbt 1.11.x - sbt/sbt#8126
