docs: Start building a named await statement. This is useful is cases when you
  have several awaits in your test and you need to tell them apart. If a
  named await timeout's the <code>alias</code> will be displayed indicating
  which await statement that failed.
  
  @param alias the alias that will be shown if the await timeouts.
  @return the condition factory
