Add description of DQ check in natural language, for alerting #116
Description
The current alerting to Slack/MS Teams is rather technical and does not contain any reference in natural language to what is being checked. Only the technical/GX expectation name (e.g. ExpectTableColumnsToMatchSet) and (if applicable) the column name are sent.
It would be good to add a text field to the DQ-definition JSON so that this can be used in the alerts sent via Slack/MS Teams to stakeholders/business. (On the technical side, we should probably add a limit to the number of characters this field can contain.)
These stakeholders could then come up with a single line-description of the DQ check, which can be put into this new field, and would enable them to more easily take follow-up actions for improving the data quality when receiving an alert.
