Currently InterpreterConfiguration is fully populated in tests while being almost empty in live product since paths are calculated. Thus some code in PythonLibraryPath only works in tests.

Persistent storage needs to know module location in order to calculate unique names with versions. We should have something like IPythonConfigurationService which then can be used to obtain actual data.

We can either completely eliminate InterpreterConfiguration and have everything rely on the interface and mock it in tests or remove some unused fields from the struct and have new service return InterpreterConfiguration properly populated.

The service can also handle changes to the configuration after pip install or user updates to the client app settings.
