extend action execution request to provide finer detail on errors

[pmuellr]

see #49219 (comment) for context

The suggestion is to change the action execution response from:

{
      status: 'error',
      message: "error in action \"{action-id}\" sending email: {message-from-service}"
}

to:

{
      status: 'error',
      message: "error sending email"
      actionId: {action-id},
      actionName: {just a suggestion, could be useful to have},
      detail: {message-from-service}
}

Not sure if adding additional "denormalization" of action info (like actionName) is really needed, but probably nice to have if it's available.

Should also look at CRUD operations, make sure those messages also don't require additional tweaking like this (don't think they will).

Is there anything in alerting that would be similar? Could be ...
