Add GraphQL setter to GraphqlServiceBuilder

[minwoox]

Motivation:
A user might want to set GraphQL directly to the GraphqlServiceBuilder which could be shared
between Expedia GraphQLRequestHandler and Armeria's GraphqlService.

Modification:

• Add the setter method for GraphQL.

Result:

• You can now set GraphQL to the GraphqlServiceBuilder.

The two properties are only provided by Armeria and the majority are necessary to build GraphQL. Too many checkState() looks messy. How about moving properties used to build GraphQL to GraphqlBuilder?

GraphqlService
  .builder()
  .graphql() // Return GraphqlBuilder
    .schema(...)
    .dataLoaderRegistry(...)
    .and() // Return GraphqlServiceBuilder
  .useBlockingTaskExecutor(true);
  .bulid();


GraphqlService
  .builder()
  .graphql(graphql) // Directly inject GraphQL
  .useBlockingTaskExecutor(true);
  .bulid()

I was actually thinking about it but GraphQL provides its own builder via new GraphQL.Builder().
Also, I found out that our builder, which is GraphqlServiceBuilder, does not provide all setters that the GraphQL provides. I think there's always a mismatch unless we keep up with the upstream change.
So I was rather thinking deprecating the setters:
https://github.com/line/armeria/pull/5269/files#diff-6b64ad742ab0aa687e003b83510d32495d933e5b3fd2a2236184d6f01bbfcc50R109-R110

Too many checkState() looks messy.

Yes, but we need it anyway because we can't just remove the setters after deprecating them. 😉

So I was rather deprecating the setters:

I agree with this idea.

[minwoox]

I've deprecated all the setters. PTAL. 🙇
