Description

This updates Data Source Lifecycle Events.

• Add event when someone opens the new data source dialog.
• Add event when someone edits a data source (on the backend) - didn't add the edited keys, but tell me if this adds value.
• Update Test Connection event to include result of test - result added in a result key.

Note: Backend-wise the name for the object_type is "datasource" and in the frontend it is "data_source", I didn't change this as it could break existing tracking, but lmk if I should.
