To Reproduce

1. Deploy openmetadata using docker compose yaml file.
2. Start openmetadata.
3. Login as admin.
4. On settings, Choose Azure SSO and Configure.
5. Provide details to configure and save.
6. Login to make sure SSO is working.
7. Restart machine (Entire machine restart is required, not just docker containers).
8. Once restart has completed, check the openmetadata_server logs using docker logs command.

Expected behavior
On machine restart openmetadata_server should start normal and be healthy with Azure SSO in place.
