[JENKINS-60409, JENKINS-60199] - Upgrade Winstone from 5.8 to 5.9 to apply Jetty 9.4.24+ regression fixes

https://github.com/jenkinsci/winstone/releases/tag/winstone-5.9

Newer versions turned out not to be mature enough for LTS so we are reverting
to latest known version.

This reverts commit ddae319a.

[JENKINS-57888, JENKINS-60821] -  Winstone 5.7: Restore java.util.logging.config.file property support and change the Jetty thread pull name

(cherry picked from commit 6c18a397)

* Upgrade to 4.2 version of Remoting.

* Upgrade to slave-installer 1.7.

* Remove multicast discovery services.

* Refine clean up with DNSMultiCast.

Doesn't need to be referenced in the other pom any more.
We need to keep the class and the property around for a while.
Jenkins Test Harness sets the property. Until we can get all
versions aligned so it isn't needed, it's best to keep the property
doing nothing.

* Deprecate remaining class fragment.

* Remove unneeded dependency.

* Improve code comments for external usages.
