Implement binding to Google Drive API to retrieve readonly docs

The source of real CVE information will be from a read-only document in Google Drive. We will need an API key for this information to be retrieved associated with our EF Google Drive. This information will be in CSV format and should be cached for at least an hour on retrieval.

This information will contain sensitive CVE data that should not be revealed to the public at least in phase 1. Only CVEs with the status Completed should be available to the API.
