Apollo link implementation used to queue graphql requests.
Link will push every incoming operation to queue.
All operations that are ready (i.e. they don't use client

client goes online
there is a new operation and client is online
operation was completed (which could result in ID updates, i.e. new
operations ready to be forwarded - see OfflineQueue class)
