[JENKINS-44930] Allow sh to return exit status, stdout and stderr all at once

Like many of the commenters on -JENKINS-26133">JENKINS-26133- I'd like to be able to capture the exit status and text written to standard out at the same time.

My current use case is calling git merge --no-edit $branches and if there was an error sending a slack notification with the output. 

The current workaround is:

def status = sh(returnStatus: true, script: "git merge --no-edit $branches > merge_output.txt")

if (status != 0) {

  currentBuild.result = 'FAILED'

  def output = readFile('merge_output.txt').trim()

  slackSend channel: SLACK_CHANNEL, message: "<${env.JOB_URL}|${env.JOB_NAME}> ran into an error merging the PR branches into the ${TARGET_BRANCH} branch:\n```\n${output}\n```\n<${env.BUILD_URL}/console|See the full output>", color: 'warning', tokenCredentialId: 'slack-token'

  error 'Merge conflict'

}

sh 'rm merge_output.txt'

Which works but isn't a great developer experience... It would be great if I could request an object that contained: status, stdout, and stderr.
