make --upstream_sync also sync the gap analysis graph progressively

[northdpole]

Issue

What is the issue?

Current gap analysis graph is 9Gb which makes it very hard to download reliably when running locally (also you shouldn't need 9Gb of data to run the project)

Expected Behaviour

Upstream sync should either download the data necessary in order to run(graph structure).
For the Gap Analysis graph it should either grab it from a place suitable for this sort of data (e.g. google public dataset) or it should load it from upstream opportunistically and then save it in the local database
