  * Override options for a task

  *   Deployment, Node, Application, Task
  *
  * A task option will always override more global options from the

  *
  * Global options for a task should be prefixed with the task name to prevent naming
  * issues between different tasks. For example passing a special option to the
  * GitCheckoutTask could be expressed like 'TYPO3\\Surf\\Task\\GitCheckoutTask[sha1]' => '1234...'.
