In addition to the existing provider data, we also want return the number of
billable units (muliplied by the rate multiplier) that each SMS provider sent
this month. This will be used on the platform admin providers page.
Since we can no longer get all the information we need from the provider details
schema, this makes a new DAO function to get all the data for the endpoint.
* Add notify user id in config
* Add dao method to get provider history versions along with tests
* BUG: Provider switching did not handle case where priorities were equal. This
* adds a fix to properly cover this case along with tests
set all existing rows to have a version of 1 (also copy across values
to populate the new provider_details_history table in the upgrade
script)
in dao_update_provider_details bump the provider_details.version by 1
and then duplicate into the history table as a new row
(done manually as opposed to the decorator used in template_history
since this is only edited in this one place and the decorator is icky)
