Introduce Docker Packaging changelogs

[oleg-nenashev]

I suggest adding experimental changelogs to the Docker packaging. Why? Docker packaging is as important as Jenkins core itself. Even if we follow the "continuous delivery" approach for Weekly releases, some changelogs could help users to track changes.

How would it work?

• We introduce meta-releases by adding GitHub tags
• We periodically cut new releases when we feel there is enough content
• Weekly releases just use the master branch and pick the latest version
• TBD: LTS packaging uses latest tags for packaging

WDYT @carlossg @batmat @slide ?

More information for users is a good thing. 👍 from me.
