Metabase alerts for fuel - emission_category assumptions

[dleard]

These alerts cannot be created until the latest cas-ggircs release has been deployed to production

The swrs carbon tax calculator makes some assumptions about the data ingested from swrs. These assumptions need to be validated via metabase alerts to let us know if there is a change.

Assumptions: A fuel is only ever associated to one emission category A fuel is never reported without an associated emission category

These assumptions are currently true for all data received beyond the 2011 reporting year.

Acceptance Criteria

• [x] add a metabase alert: Fuel has > 1 emission_category
• [x] add a metabase alert: Fuel has a fuel_amount and no emission_category (year > 2011) (these may end up being one alert)

Looks good to me. For those alerts (we have one for new fuels as well), perhaps we should create functions/views that run the sql command, so that we can test them with pgTap
