[JENKINS-42627] French translation for CLI

[JENKINS-42724] - Restore the windows-service/jenkins.xml resource to restore compatibility with windows-slaves 1.2 (#2803)

* [JENKINS-42724] - Restore the jenkins-slave.xml file

Windows Slaves plugin performs a direct access to the resources bundled into the core.
Hence the file removal was a bad idea though I have not seen the issue in automatic tests and ATH.

This change also was a last-minute change in https://github.com/jenkinsci/jenkins/pull/2765/ in order to address suggestions from @daniel-beck, hence I didn't test it properly

* [JENKINS-42724] - Update the Windows Agents plugin dependency to 1.3.1

* [JENKINS-42724]  -Revert the war/pom.xml upgrade

* JENKINS-42319: Fix broken compareTo method of Run

Previous implementation relied on fact that users always compare run
objects with same parent. But this is not always the case.
So, it was not safe to put runs from different parents to TreeSet, i.e.

* Make comparasion more performance friendly

Save after calling setSecurityRealm or setAuthorizationStrategy

* Enhance CLI HTTP proxy support

Fix few issues around proxy support in CLI:

* make proxy support work with recent Squid version which reply with HTTP/1.1 even if request is HTTP 1.0
* close the socket connected to the proxy if the connection failed
* output an error message when proxy connection failed
* don't do a reverse DNS lookup, instead use the host string provided in X-Jenkins-CLI-Host headers (we don't know if the DNS resolver on the
proxy will be able to resolve the name correctly, or like us).

* Use stdout to output CLI proxy connection error message

* Use the logger to output the error message, not System.out

* Add a 'verbose' option to the CLI to turn logging on

This should help people diagnosing connection issues with the CLI.

* [JENKINS-42191] Set log level to FINEST when -v is passed

Update SSHD Core to 1.10.

Clarify PermissionGroup.owner is @Nonnull

Depending on what seems to have been timing conditions, connectNodeShouldSucceedWithForce could fail with a cryptic message.
Found an error in the launch log:
java.lang.IllegalStateException: Already connected
	at hudson.slaves.SlaveComputer.setChannel(SlaveComputer.java:567)
	at hudson.slaves.SlaveComputer.setChannel(SlaveComputer.java:390)
	at hudson.slaves.CommandLauncher.launch(CommandLauncher.java:132)
	at hudson.slaves.SlaveComputer$1.call(SlaveComputer.java:262)
I think the slave was being launched in the background, and then the test tried to disconnect and reconnect it.
Perhaps if these actions overlapped in time, the loose locking semantics of SlaveComputer.setChannel could cause the error.

Don't wrap the InterruptedException without unwrapping

[FIXED JENKINS-34691] Add the ability for ItemListeners to veto copy operations

Permission.owner is already marked @Nonnull, and
is built using PermissionGroup.owner.

Fix test to avoid saving Jenkins.securityRealm/authorizationStrategy after we rewrote $JENKINS_HOME/config.xml, clobbering it.
https://github.com/jenkinsci/jenkins-test-harness/pull/53 would simplify test code a bit.
