Jenkins: Present most recent interesting build info

[gerhardol]

Proposed changes

Jenkins can start many builds for a commit, for instance for the branch and the pull request.
In some occasions the subsequent build(s) are aborted immediately, getting status NOT_BUILT
It is of course possible to abort builds too

The Jenkins build adapter presents the status for the latest build started for a commit regardless if it is complete or not.
This tries to present the most interesting status instead.

• Cleanup from Re#, some manual adjustments
• The intervall for retrieving running builds was changed to two minutes in 3fcb478, but the full day obervable was kept at one minute

Do we need the class at all?

[gerhardol]

Yes, it stores the latest known build time for a project url. The adapter first asks for last build time, then requests the full data with all builds if there is anything new (that is more to save the server than the processing in the plugin).

[gerhardol]

But you maybe meant why use a class, why not long directly?
I will change to that
Making a few other touchups, want to test this on Monday/Tuesday before pshing and initiates a merge

LGTM

JenkinsAdapter.cs(510,13): error SA1508: A closing brace should not be preceded by a blank line

It takes time to test when the dev machine is accessible at night and test by day.
That also caused some more tweaks...
Squashed the first commits, the new changes separately, plan to squash that too in a couple of days (not too hard to review).

Hello @gerhardol!

Because you've given me some instructions on how to help merge this pull request, I'll be modifying my merge approach. Here's how I understand your requirements for merging this pull request:

• I won't merge this pull request until after the UTC date Wed, 30 Sep 2020 22:00:13 GMT, which is in 1 day

If this doesn't seem right to you, you can tell me to cancel these instructions and use the auto-merge policy that has been configured for this repository. Try telling me "forget everything I just told you".
