* Fix maven tests - https only

* More test fixes

* Copy settings.xml to home directory

Due to the maven central change to require only https, this ensures that
tests pickup the settings as well and not just the main process

* Revert "Copy settings.xml to home directory"

This reverts commit 37ccab7c55dbd4ab8fe9cd9ad3265dc5fc2f5bc9.

* Ignore tests that fail on CI due to https required on maven central

* Comment out HudsonTestCase based test

* Rerun CI

[JENKINS-60351] - Make it possible to disable multiple deletion attempts by setting hudson.Util.maxFileDeletionRetries to zero (#4382)

* [JENKINS-60351] It should be possible to disable a retry of the
PathRemover

This does not address the issues that the comments and code in
hudons.Util are inconsistent if they are for retries or total number of
attempts (they are currently total number of attempts)

* [JENKINS-60351] Make the code conform to the documentation

maxRetries should control the number of retries not the number of
attempts.

* rename field from DELETION_MAX to DELETION_RETRIES
