Consider caching synced repos #2
Description
Context
The downloaded nuget packages are cached in the user profile.
We can similarly cache the synced source codes. The downside would be the need of copying those to the requested destination directory (and hence slowdown for the first request), as sources might get edited in the destination directory.
This would be beneficial under assumption that the same package (even different version - as we can reuse code and switch to different commit after copying) is being resolved multiple times in the same environment (which would hold, if this would became part of the 'package sourcing' as a way of resolving nuget package)
