Remove temporary medical records page and feature toggles

Transitional Medical Records

The mhv_transitional_medical_records_landing_page feature toggle is ON while the new Medical Records application is still in development.

This toggle will need to exist and remain ON until the Medical Records app on MHV-on-VA.gov is launched and we're directing 100% traffic to that app.

Notes

• MAKE SURE vets-website toggles are removed first before merging changes to vetrs-website
• The redirect from the temporary medical records page could be done in app or via the redirects in the devops repo.
  • https://github.com/department-of-veterans-affairs/devops/blob/master/ansible/deployment/config/revproxy-vagov/vars/redirects.yml
  • https://depo-platform-documentation.scrollhelp.site/developer-docs/routing
• When the feature toggles are OFF (or at 0%), it can be removed.
• [ ] Make sure toggle is OFF or at 0% in all environments
• [ ] Remove feature toggle from vets-website
• [ ] Merge changes and wait for changes to propagate to envs.
• [ ] Remove feature toggle from vets-api
• [ ] Run Flipper.remove(XXX ) in development (dev.va.gov).
• [ ] Run Flipper.remove(XXX) in staging (staging.va.gov)
• [ ] Run Flipper.remove(XXX) in sandbox
• [ ] Run Flipper.remove(XXX) in production (va.gov)

Per @carlosfelix2, we might also consider replacing the toggle with mhv_medical_records_to_va_gov_release, which looks like the Medical Records teams release toggle.
