Write a Cairn plugin that gathers certificate information
We'd like Cairn to report on the amount of certificates generated. This data is not present in the default data set fetched/stored by Clickhouse (Clickhouse is a DBMS that is working as a middle layer between OpenEdx and Cairn), so we need to write a (python) plugin that gives it access to this data.
