LG-163 Turn on agency based UUIDs

[stevegsa]

Why: We need to share agency-specific UUIDs as well as facilitate sharing of an agency’s UUID with other agencies. We also need a way to count the unique number of users for an agency for billing purposes

How Change the feature flags associated with agency based uuids. Specifically we are changing the environment variables enable_agency_based_uuids and agencies_with_agency_based_uuids to include all agencies.

Hi! Before submitting your PR for review, and/or before merging it, please
go through the following checklist:

• For DB changes, check for missing indexes, check to see if the changes
  affect other apps (such as the dashboard), make sure the DB columns in the
  various environments are properly populated, coordinate with devops, plan
  migrations in separate steps.

• For route changes, make sure GET requests don't change state or result in
  destructive behavior. GET requests should only result in information being
  read, not written.

• For encryption changes, make sure it is compatible with data that was
  encrypted with the old code.

• For secrets changes, make sure to update the S3 secrets bucket with the
  new configs in all environments.

• Do not disable Rubocop or Reek offenses unless you are absolutely sure
  they are false positives. If you're not sure how to fix the offense, please
  ask a teammate.

• When reading data, write tests for nil values, empty strings,
  and invalid formats.

• When calling redirect_to in a controller, use _url, not _path.

• When adding user data to the session, use the user_session helper
  instead of the session helper so the data does not persist beyond the user's
  session.

• When adding a new controller that requires the user to be fully
  authenticated, make sure to add before_action :confirm_two_factor_authenticated.

When do we want this to take effect?

The plan was to send it out with the normal prod deploy for the current sprint and run some rake tasks in prod beforehand.
