* propagate session config

* round of cleanups

* minor cleanup

* propagate session context to tasks

* propagate session config

* scheduler exposes config provider

* remove public references to configs

* remove configuration options

* fix clippy

* add test to show object store registry configuration

* fix tests

* make test not failing due to environment settings

* fix python compile error

* add few more comments on object_store test

* disable testcontainers and standalone

* fix compile issue in flight_sql

* minor cleanup

* minor changes in examples
