Make source freshness test descriptions configurable

[waligob]

Is your feature request related to a problem? Please describe. It appears that the test description for source freshness tests is a hard-coded string.

Describe the solution you'd like It would be helpful if this could be made configurable via a property under the meta block.

Describe alternatives you've considered As a workaround, we're appending metadata to sources[].tables[].description, but that requires navigating from the test results to Elementary's lineage graph, and then selecting "..." > "Node info" in order to view that metadata

Additional context

Would you be willing to contribute this feature? Yes!

Hey @waligob ! 🙂 This string is the default in case there's no customized description. Try adding this:

  - elementary.freshness_anomalies:
          meta:
              description: "Your own test description"

Let me know if this helps.

@NoyaOffer Given the following freshness test configuration, where would your snippet go if I wanted to override the default description?

sources:
  - name: auth0
    loader: Stitch
    tables:
      - name: auth0_export
        description: >
          This table contains an export of our auth0 database.
          auth0 is used for user authentication and is our source for registered users
        loaded_at_field: _sdc_batched_at
        freshness:
          error_after:
            count: 28
            period: hour
