feat: add Relay ID translation in mutation and queries (#109)
Adds a new option for queries and mutations that defines which arguments or
attributes will use a global Relay ID and their type. This allows automatically
decoding them before hitting their action.

This paves the way to automatic translation derived from the arguments, which
will be implemented subsequently.
