Declarative: agent dockerfile fails when agent inside stage

Change By:	Liam Newman

In a project with a {{Dockerfile}}, This pipeline succeeds:

{code:language=groovy}
pipeline {
    agent {
        dockerfile true
    }
    stages {
        stage ('Build') {
            steps {
                sh 'echo "hello"'
            }
        }
    }
}{code}

This pipeline fails:

{code:language=groovy}
pipeline {
    agent none
    stages {
        stage ('Build') {
            agent {
                dockerfile true
            }
            steps {
                sh 'echo "hello"'
            }
        }
    }
}
{code}

The reason this happens is that the agent inside a stage step does not do checkout scm automatically.  This is very confusing behavior.
Agent initialization should be consistent whether at top or inside a stage.

The reason this happens is that the agent inside a stage step does not do checkout scm automatically.  This is very confusing behavior.
Agent initialization should be consistent whether at top or inside a stage.

The following also works, because of {{reuseNode true}}, but dockerfile would never work without that when inside a state (due to JENKINS-41605).
{code:language=groovy}
pipeline {
agent any

    stages {
        stage ('Build') {
            agent {

dockerfile {
reuseNode true

                }
            }
            steps {
                sh 'echo "hello"'
            }
        }
    }
}
{code}
