transports
  Bolt uses transports (also known as protocols) to establish a connection
  with a target in order to run actions on the target. The default transport is
  SSH, and you can see available transports along with their configuration
  options and defaults at http://pup.pt/bolt-reference.
   
  You can specify a transport for a target by prepending '<transport>://' to
  the target's URI. For example, to connect to a target with hostname
  'example.com' as user 'Administrator' using the WinRM transport, you would
  pass the following to the target flag:
      winrm://Administrator@example.com
   
  You can also specify a default transport for all targets by passing the
  '--transport' flag on *nix systems and the '-Transport' flag in Powershell.
  Finally, you can set the transport for a target in the inventory. For more
  information about the Bolt inventory, run 'bolt guide inventory'.
