Allow insights data to be exported to CSV
The Quality dashboard allows data that drives a chart to be exported to CSV. It could be useful to provide a similar feature to supply the data behind each chart on each dashboard on the insights pages
## Proposal
- Add a link to export to CSV to Native Insight charts leveraging existing email CSV functionality.
## Details
- The query for each chart within a dashboard can be different, though charts within a dashboard are normally centred around a particular label/theme (such as bugs, features)
- The export link should be available per individual chart
