This version of the client removed the request method, path and body from the encode and decode methods.
The biggest changes here is to the unit tests.
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.
