Ideally all the primary keys in the db would be UUID in order to guarantee unique ids across distributed dbs.
This updates the services.id to a UUID. All the tables with a foreign key to the services.id are also updated.
The endpoints no longer state a data type of the <service_id> path param.
All the tests are updated to reflect this update.
The thing to pay attention to is the 0011_uuid_service_id.py migration script.
This commit must go with a commit on the notifications_admin app to keep things working.
There will be a small outage until both deploys have happened.
/service/<service_id>/api-key/renew has been renamed to /service/<service_id>/api-key
/service/<service_id>/api-key now creates a token and no longer expires the existing api key.
Moved test for this endpoint to it's own file.
