• Private_key supplied for remote_actions is now used to auth correctly. private_key argument
  should be the contents of private key file (of user specified in username argument). (bug-fix)
• Last newline character ('\n') is now stripped from stdout and stderr fields in local
  and remote command/shell runners. (improvement)
• Fix sensor container service so the config argument is correctly passed to the sensor
  instances in the system packs. Previously, this argument didn't get passed correctly to the
  FileWatchSensor from the system linux pack. (bug-fix)
• Make sure sensor processes correctly pick up parent --debug flag. This makes debugging a lot
  easier since user simply needs to start sensor container with --debug flag and all the sensor
  logs with level debug or higher will be routed to the container log. (improvement)
