    Support action_execution deletion

    With this patch, users can perform operation as following:
    DELETE http://127.0.0.1:8989/v2/action_executions/<action_execution_id>

    NOTE:
    * Added a new config item 'allow_action_execution_deletion', with default
      value 'False'.
    * The 'allow_action_execution_deletion' item is set to 'True' for
      functional testing.
    * Only ad-hoc action-execution can be deleted.
    * Only completed action execution can be deleted.
