Caching on gateway LocalGraphQLDataSource level does not seem to work

[dazlious]

Issue Description

I am running into an issue where the apollo supergraph's caching does not work, but the underlying supgraphs just work fine.

When executing

query a {
  foo
}

I get response header cache-control: no-store

When executing

query b {
  products {
    name
  }
}

I get response header cache-control: max-age=500, public

When executing

query c {
  foo
  products {
    name
  }
}

I get response header cache-control: max-age=500, public

Problem 1: I cannot seem to make the cache work for query foo
Problem 2: When querying foo with any other cached subgraph query, it just applies the cacheControl of that query to the whole response, but IMO it should compute the correct restrictive one.
