insights: 1 click debug information about a code insight

Created by: coury-clark

To facilitate easier support requests, I propose we build a 1 click export button on a code insight (possibly behind a debug mode? ?debug that will export as much relevant information about the code insight (or the instance) as possible.

Some things we may want to export:

• Insight view metadata
• Insight view filters
• Insight view permissions
• Insight series metadata
• Insight series error counts (this might be tricky due to cardinality constraints)
• Debug events (tracking things like time we started backfill, time backfill finished queuing, etc)
• Backfill statistics (how many repos were queued, compressed, skipped, etc)
