Add support for GraphQL query editor #489
Description
The GitHub data source utilises various GraphQL queries in the background. It would be great if, as a user, I could also specify a freeform GraphQL query.
This would allow the following:
- Querying of data that is not supported by default in the data source without waiting for new query types to be added.
- Improved filtering/aggregating/grouping of data with greater flexibility.
- Reduced dependence on the Infinity data source for more complex querying.
