What Does This PR Do?

• Added language code to auth flow logging events ('auth_language' field added to numerous auth flow log events)
• Extended AuthflowUUID model - adding field 'auth_language' - this is need to persist lang code across sessions
• Tweak testclient Authorization page - adding button "Authorizate with beneficiary (medicare.gov login in Spanish)" which will append a lang=es parameter at the end of the authorize URL...

What Should Reviewers Watch For?

If you're reviewing this PR, please check these things, in particular:

• TEST

• Local Test

  • Checkout PR and spin up a local BB2 server
  • Aim browser at localhost:8000 and go to test client page
  • Start AUTH flow (targeted at medicare.gov Spanish login) by hitting Auth in spanish button as below:

  • 

  • Following through the data access grant steps, and collect logging at the std out of BB2 server start terminal
  • Search through the captured logging output for "auth_language": "es" to verify that all authorization logging events are having language code (which will be used by Splunk search for auth flow aggregation on lang code.

• Test on LLE (e.g. TEST env)

  • Deploy the PR to LLE (e.g. TEST) - Need pre deploy migration (AuthflowUUID model change)
  • Test the scenarios as with local test, however do not use testclient (TestApp) since it is excluded by Splunk auth flow dashboard, instead create an application and use e.g., BB2 sample client to hit with authorization flow.
  • Observe the splunk dashboard - toggle the "Language" drop down to see flows with the selected language...
