Jenkins self-update

[chrisdecker1201]

Hi @geerlingguy 🙂,

I'm wondering if it's possible to add something like jenkins_disable_restart.

I want to update Jenkins by using ansible and a Jenkinsfile. Therefore, I need to make a safeRestart call to the CLI instead of a "hard" reset during the run of the pipeline.

I'm willing to try to implement this, but I wanted to make sure it had a chance of being merged.
