[WIP] feat: GraphQL support for Frappe

[pipech]

Adding GraphQL support for Frappe

Adding GraphQL to Frappe using Graphene GraphQL libary in Python

Since GraphQL is strong typing, we won't try to add some check box to DocType to enable GraphQL , instead we will aim to create object such as FrappeObjectType to fetch frappe doctype and convert to Graphene object.

Developer will have to create manually create FrappeObjectType to enable GraphQL for each Doctype.

Schema should be create at server start (or some sort), it should fetch all Graphene object from each installed apps and then add it to Root schema.

Todo list

• Mapped Frappe Type with Graphene types
• Add resolver to get FrappeObjectType for link field
• Fetch all Graphene object from each installed apps and then add it to Root schema
• Solve n+1 problem

@surajshetty3416 Could you keep it open just for now, since I'm planing to use it on version 12 and will develop on version 12.
After I'm finished developing I'll close this pull request and re-open it on version 13.

@pipech and are you still working on this? Does the code fully work, or did you run into any issues that made you think that this implementation is not as easy as expected?

@rmehta @surajshetty3416 do you know of any other projects that are working on a GraphQL implementation at the moment?
