GraphQL: Combine with upload service

[sent-hil]

In Docker Compose, the upload service is two separate lambda functions, we are no longer using lambda so these need to be migrated over to a monolith service.

@darpham so this turned out to be more difficult than I originally thought; the backend app is its own apollo server to which I can't add new routes

there are two solutions:

• run apollo server and express in the backend container and use nginx to reverse proxy within the container
• use https://www.npmjs.com/package/apollo-server-express and make the upload function a middleware
• keep upload as its own server and container

the latter is far, far easier :) what do you think?

to close loop on this, we decided to go with option 3 and keep upload service in its own container
