[maven-release-plugin] prepare for next development iteration
updated changelog as a part of the release
New ssh-slaves needs new ssh-credentials as well.
Otherwise you get a NSME when trying to launch a slave.
Amends vjuranek’s 64ff047 in 1.509.1.
Update parent so that we get a newer maven-hpi-plugin; 1.93 just does not work in this LTS for plugins.
(hpi:run fails to load the plugin itself, claiming that ui-samples is missing.)
[FIXED JENKINS-4543] Identify the short name of the plugin from the manifest.

(cherry picked from commit f1669601e4bd607ffa8a809e109f1ad0c79244b1)

[JENKINS-17775] If MavenProject.getParent throws ISE during fingerprinting, report it but at least proceed.
Proper fix is to ensure that the model resolution uses the same environment as the actual build,
or is otherwise more lenient about finding the parent (e.g. enables plugin resolution).
