In apollo federation, we may be asked for data about a list of entities.
These can typically be resolved in parallel, just as with sibling fields
in ordinary GraphQL queries. Now we do!
I also changed the behavior such that if one lookup fails, we don't
cancel the others. This is more consistent with the behavior of other
resolvers, and is more natural now that they execute in parallel. This,
plus panic handling, required a little refactoring.
The examples probably give the clearest picture of the changes. (And the
clearest test; the changed functionality is already exercised by
integration-test.js
as watching the test server logs will attest.)Fixes 99designs#1278.
