separate servers for graphql, rest, admin

[rogueturnip]

As I was setting up things I was thinking it might be very handy if each of the services could be set up as different servers rather than all under the one express app.

This would allow, potentially for putting the containers on different hosts to handle the calling capacities differently or add different authentication permissions.

Optimally could be to expose the graphql schema/resolvers so they could be used inside an Apollo server instance which would allow for serverless setup (AWS lambda).

I think one thing that would have to happen for this to work would the api servers would have to learn the configuration from the administration server.
