Review Comment:
Looking at the comments/code I looked at below I have some doubts and
different idea.
I think the original permissions for task endpoints were just wrong:
```python
@security.requires_access(
[
(permissions.ACTION_CAN_READ, permissions.RESOURCE_DAG),
(permissions.ACTION_CAN_READ, permissions.RESOURCE_TASK_INSTANCE),
],
)
```
It really should be:
```python
@security.requires_access(
[
(permissions.ACTION_CAN_READ, permissions.RESOURCE_DAG),
(permissions.ACTION_CAN_READ, permissions.RESOURCE_TASK),
],
)
```
I know we do not have "RESOURCE_TASK" - but this should be really how it
should be done inititially. Those endpoints do not access task instance nor
dag_run access - they just add `task` definition. I think we wrongly had only
one `TASK_INSTANCE` resource where we should have two different resources for
those.
IMHO - we have the opportunity to fix it (and that will allow us to avoid
adding tuple handling from my above proposal.
Why don't we simplify it all by
* `DagAccessEntity.DAG`
* `DagAccessEntity.TASK`
* `DagAccessEntity.RUN`
* `DagAccessEntity.TASK_INSTANCE`
We should only need to specify TASK_INSTANCE entity. In FAB implementation
we could map:
* DagEntity.TASK => resource.TASK_INSTANCE and
* DagEntity.TASK_INSTANCE -> resource.DAG_RUN + resource.TASK_INSTANCE
The fact that sometimes we specified "read" for DAG_RUN and "write" to
"TASK_INSTANCE" resources was I think a mistake. I can't imagine situation
where we would like to limit the user from writing to DAG_RUN where the user
should be able to update TASK_INSTANCE. So this would automatically fix the bad
permissions we had originally for those endpoints.
