I think the main idea here was to delegate the authentication to what
connexion provides (it has various authentication plugins). And I agree
authorization should be addressed in the design as it cannot be solved by
connexion "standard" plugins nor Open API definition - this is more of
application choice.

I think we should get som simple, yet configurable mechanism for
authorization - which should be similar to what we have in FAB now but we
should learn from its problems. I think we should first agree on the
principles and features we want to achieve and then decide how to proceed.

What I think this authorization system for the API should/should not do
(this is my personal view - others might have different opinion, so feel
free to express yours):

* it should not be view-centered but API endpoint-centered.
* It should allow assigning the users to different Roles - example roles -
"Admin", "Editor", ....
* It should allow to bundle several API calls together and assign rights to
the API "bundles" to the user roles. Example "connections", "dags", "pools"
.... . Again - those should be per API not per View.
* the Bundles should have "Read"/"Write" access types
* the Roles do not have to have UI to manage it - it could be done by a
configuration file
* it should be discoverable - the UI code should be able to discover which
API Bundles it has access to (this will allow implementing dynamic views
that will adapt to the different Roles).
* optionally the users should have the capability of constraining rights to
certain resources per "resource" (so for example access to some dags only).
We could implement a very simple 1-1 mapping of the current "owner"
approach, and in the future, we could implement "User Groups" and have
"Resource-per-Group" authorization. I don't think it is for Airflow 2.0 and
we should add it later (this is application level rather than API level
feature).
