Lingxian Kong f2eaea5a12 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.

Implements: blueprint mistral-action-execution-deletion
Closes-Bug: #1488157
