Description

Discovered during running on pull request workflows when not related image retrieval script was checked in.
Integration tests are not starting after many attempts.Fails on setup:

 /usr/bin/sg microk8s -c juju bootstrap --debug --verbose microk8s github-pr-08a8c --model-default test-mode=true --model-default automatically-retry-hooks=false --model-default logging-config="<root>=DEBUG" --agent-version=2.9.34 --bootstrap-constraints=""
  ERROR cannot load ssh client keys: mkdir /home/runner/.local: permission denied
  Error: The process '/usr/bin/sg' failed with exit code 2

This PR has the logs/traces for failing tests #135

Two problems were observed:

• Failure to start tests due to updated Juju 3.1.5?
• Charm build and integraton test failures described in python dependencies are affecting the CI of multiple CKF repositories bundle-kubeflow#648

Need to review and address failing tests.

In order for Dex inb track/2.31 to pass CI, requirements must be updated. Updating requirements requires to bump SDI. This in turn requires code change to dex in track/2.31. This is the commit that has needed change.
Code change required:

After debugging session it was concluded that solutions proposed in canonical/bundle-kubeflow#648 cannot be used in Dex's case. New possible approach is summarized in the same issue to keep information in one place.
