Add the ability to view some important metrics of assessing how CTSM development is proceeding

[ekluzek]

It would be helpful to have some ways of viewing development metrics of how things are going. There are limited
charts in insights, and you can only easily do charts with existing project boards.

There's a research group on Software Development called DORA that has a set of metrics to look at:

https://dora.dev/

There's four metrics they recommend

https://dora.dev/guides/dora-metrics-four-keys

The metrics look at development throughput and stability. With two for each, here is a definition of them from the above page:

Throughput
Throughput measures the velocity of changes that are being made. DORA assesses throughput using the following metrics:

Change lead time - This metric measures the time it takes for a code commit or change to be successfully deployed to production. It reflects the efficiency of your delivery pipeline.
Deployment frequency - This metric measures how often application changes are deployed to production. Higher deployment frequency indicates a more efficient and responsive delivery process.
Stability
Stability measures the quality of the changes delivered and the team’s ability to repair failures. DORA assesses stability using the following metrics:

Change fail percentage - This metric measures the percentage of deployments that cause failures in production, requiring hotfixes or rollbacks. A lower change failure rate indicates a more reliable delivery process.
Failed deployment recovery time - This metric measures the time it takes to recover from a failed deployment. A lower recovery time indicates a more resilient and responsive system.

There is a github action for doing this in github Marketplace:
