Investigate reducing db queried fields based on gql request

[ermish]

Summary

In apollo, you can choose what fields you want returned. Currently, we query all of them from the db. There's an optimization to reduce what's queried from the db to only include what the user requested.

for example, if they queried facilities without healthcare professionals, we shouldn't do the extra db call
