What does this PR do?
This PR makes it possible to reinstall packages even if the files from a previous installation of the same version of the package is stil in use. In that case it checks that the directory contains all the expected files and copies any missing file.
The change is scoped to windows for now, to minimise the likelihood of introducing a regression and because that need hasn't surfaced on linux yet.
Motivation
Make package installation more resilient on windows.
Describe how you validated your changes
The new code is unit tested and the behavior of the datadog-installer is checked by numerous E2E tests.
Possible Drawbacks / Trade-offs
This breaks an exisiting behavior that starting an experiment for a package already installed will fail. Is that really a desired property?
