Cold Start

Hi @Quantumplation,

It will require quite a few changes probably, like in your discussions on #231.

I would start with adding something parallel to UpdateSchema that can load a serialized schema and save one to storage periodically.

Then change the startup in Main to trigger that first before starting the periodic update goroutines.

That's where I started, but I wasn't sure how to construct an ExecutableSchema from a string; we make a bunch of requests to other services, and then rebuild the merged schema from the ASTs, but I don't see where the ASTs get built from raw text.

Have you looked through the gqlparser library, it's mostly in there, it doesn't have many helper methods but you can read schema sources into a string and then use something like:

gqlparser.MustLoadSchema(&ast.Source{Input: str})

to get an *ast.Schema.

The initial creation of ExecutableSchema is in Config.Init so it might be more fitting to put the (de)serialisation there.
