Initial PR up at https://github.com/jenkinsci/pipeline-model-definition-plugin/pull/58

Still debating also adding a shell script that you can download and run without needing to have CLI SSH port access to the master. Haven't decided yet.

Code changed in jenkins

Log:
[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.

Hi, I'm having trouble finding the CLI. I'm using docker.

$ cat Dockerfile.pipeline 
FROM jenkins:2.46.1-alpine

RUN /usr/local/bin/install-plugins.sh \
        pipeline-model-definition

When I run the image, I can't find declarative-linter anywhere. Am I missing an install step?

thanks,
