title: Golang cobra CLI - get the currentl running subcommand
body: <p>Does cobra store the name of currently running sub-command somewhere? E.g. if user started the tool with commands like:</p>
  <ul>
  <li>tool sub-command -flag1 -flag2, etc.</li>
  <li>tool -globalflag1 sub-command -flag1 -flag2</li>
  </ul>
  <p>is it possible to determine inside the program which sub-command is used from some variable or method?</p>
