Jenkins dependencies: upgrade

[sbesson]

This PR reviews a few of the Jenkins dependencies in devspace to catch up with latest security releases and bring them as close as possible to the deployment state of https://ci.openmicroscopy.org/.

Changes include:

• JDK is bumped to 8u152 to prevent the need for authentication into the Oracle website
• Jenkins is bumped to 2.46.3, the last LTS version before the Java 8 requirement
• various Jenkins plugins versions are updated to include various security fixes and match the state of https://ci.openmicroscopy.org.
• the Jenkins CLI is disabled

To test this PR:

• either spin up a new devspace or log in to a devspace deployed with this PR
• check there are no security warnings under Manage Jenkins
• optionally, review the list installed Jenkins plugins on https://ci.openmicroscopy.org and check the new versions are in agreement

As part of the prep for the training
I am going over the devspace readme (few changes made already)
new error preventing the generation of a devspace:

TASK [Docker external access security group] ***********************************
fatal: [localhost]: FAILED! => {"changed": false, "failed": true, "msg": "Invalid cloud configuration: The plugin password could not be found"}

The error is not related to this PR, more the status of the various moving parts

[jburel]

Similar to https://ci.openmicroscopy.org

The common plugins have the same versions
More plugins are available in CI master

[jburel]

current version is 152

Everything is in place and the change will simplify the new generation of new devspace
I will still indicate the step required when a new version of Java is installed

Any objection to get this PR merge?

Combine with the recent work done during training
Everything is working.
