Investigate best path to store interface implementations

[jthandy]

Currently we are storing interface implementations as comments on tables like this:

COMMENT ON VIEW {schema}.visitoractivity IS 'timeseries,funnel,cohort';

This is likely not the ideal mechanism to accomplish this table-to-interface mapping and we should give more thought to it.

• What exactly are the goals of having this? Should be clear about what we are trying to accomplish.
• Evaluate having this information stored within the schema as opposed to living outside the schema in code.
• What's the best technical solution to accomplish the goals defined above?

Interfaces are a hard question that we're struggling with to evaluate dependencies. Storage of this information is the least of the concerns :) This is important, but it needs to be handled structurally as a part of dbt.
