docs: Get a unique, time-based identifier for a deployment
      that optionally, also includes some sort of version number
      or release.
  
      If a version is supplied, the release ID will be of the form
      '$timestamp-$version'. For example:
  
      >>> get_release_id(version='1.4.1')
      '20140214231159-1.4.1'
  
      If the version is not supplied the release ID will be of the
      form '$timestamp'. For example:
  
      >>> get_release_id()
      '20140214231159'
  
      The timestamp component of this release ID will be generated
      using the current time in UTC.
