Add @client directive support in VS Code

[tomsseisums]

I am trying to set up IDE to ease GraphQL development for our junior team members. And not gonna lie, to help myself too.

I have a query that operates on client state:

import gql from 'graphql-tag';

export default gql`
mutation LoadProfile($profile: ProfileInput!) {
  loadProfile(profile: $profile) @client {
    accessToken
    avatar
    name
  }
}
`

Though, removing the @client does not invalidate the query.

Is this expected behaviour or I have misconfigured something or it's a bug?

Otherwise, everything seem to be working - autocompletion for both client queries and remote queries, go-to definition, validation, for instance:

Just that dropping @client from client queries doesn't throw anything.

I don't think there is support for knowing if a field comes from a remote source or a client source in vscode apollo yet.

Good news! This is actually being worked on right now by @jasonpaulos! I'll assign him and he can add his PR to this issue when one is open 🙌
