Automated lead time statistics

[mathisrichter]

User story

As a Lava maintainer, I want to know how quickly we resolve support requests on Github to move toward shorter lead times in a data-driven way.

Note:

• Lead time is measured by the time elapsed between opening an issue and the issue being resolved.
• We need to figure out how to deal with "closing" discussions.

Conditions of satisfaction

• Lead time on bug reports are captured (all repositories)
• Lead time on feature requests are captured (all repositories)
• Lead time in discussion forum are captured (all repositories)
• Lead times are visualized in a graph
• A summary report can be generated for a given time frame.
• Possibility to filter for support requests originating from the wider community vs. from within NCL.

Acceptance tests

• to be determined
