Code changed in jenkins
User: Andrew Bayer
[FIXED JENKINS-39923] Add a CLI endpoint for the linter
Can be used like:
ssh -p [sshd port on master] localhost declarative-linter < Jenkinsfile
Tweaks still needed for permissions (right now, it's anyone with read
access, which, I think, is OK) and possibly reading the file reading
than just taking it from stdin.
