teleport-setup: Consider leveraging GitHub Cache #55
Description
Today, we leverage the confusingly named tool cache for the Teleport binaries. This isn't a shared cache between runners, but, a cache local to a specific runner. The tool cache effectively is only useful for self-hosted runners.
We could additionally leverage the GitHub Cache - this would be shared between runs: https://github.com/actions/cache
This would have a few benefits:
- This should reduce the time it takes for the action to run.
- Reduce the actions reliance on our CDN being available.
- Reduce our costs in terms of our CDN.
