Switching to official docker jenkins/jenkins image

[vsilverman]

This PR continues updates, started by PR #3843 .
Now besides Tutorials Build Tools updates cover Installing Jenkins and Pipeline chapters of Jenkins Handbook and supports Blueocean chapter.

Current PR is an attempt to fix such issues as #3315, #3583, #3650, and others, related to using new official Jenkins docker image.

Would like a review from @jvz to assess the alternatives. He made the most recent improvement and found a way for us to use the Docker in Docker image with Blue Ocean.

A few items that need to be corrected. Unfortunately, I don't know how to have command line access to the docker socket through the Docker CE cli without running as the root user. I assume it will require that the user inside the Docker container must have Docker permissions ?

That looks right so far.

@vsilverman I ran interactive tests and made changes that I've pushed as proposed changes

[jvz]

I forgot to leave a final review, but these updates look great!

[MarkEWaite]

Thanks @jvz . I'm preparing a pull request that will correct some mistakes that I detected and will update the tutorials to use the same technique. Special thanks to @vsilverman for finding a path forward.

See #3919 for the next step in the evolution of the tutorials and the installation guide. Still need to find a way to deduplicate the content that is the same in _docker.adoc and _docker-for-tutorials.adoc. Some form of setting one or more variables in the tutorial header to provide the extra content. That will be for a future pull request.
