external persist queries file

[veeramarni]

I would like to see if we can add extracted queries through import if we running front-end and back-end in separate containers.

For example import <package>/extracted_queries.json

Right now it fails with below error when persist queries json file is not found.

@veeramarni Does these containers share some part of filesystem?
If yes, I think it is doable, but support for such setup should be added to spinjs, Pull Request will be welcome:
