Ability to generate only root interface with all queries/mutations/subscriptions

[jxnu-liguobin]

Issue Description

Describe your bug in detail.
option ApiRootInterfaceStrategy default value is SINGLE_INTERFACE . literally, only one resolver query and resolver mutation will be generated.
I tried both gradle and SBT, and the results were the same.there have generated resolver for every graphql query.
As a result, I have too many useless classes under the API package, because I only need a resolver that contains all interfaces.

Steps to Reproduce

List in detail the exact steps to reproduce the unexpected behavior.

Expected Result

when set apiRootInterfaceStrategy := com.kobylynskyi.graphql.codegen.model.ApiRootInterfaceStrategy.SINGLE_INTERFACE, only a query resolver java file will generate.

So, can I not generate other resolvers?

Actual Result

Explain in detail what behavior actually happened.

Your Environment and Setup

• graphql-java-codegen: E.g.: 2.4.1
• Build tool: E.g.: Maven
• Java tool: E.g.: Oracle 8u241
• Mapping Config: E.g.:

<configuration>
    <outputDir>${project.build.directory}/generated-sources/graphql</outputDir>
    <packageName>io.github.kobylynskyi.graphql.model</packageName>
</configuration>

@jxnu-liguobin it's not a bug.
Property apiRootInterfaceStrategy is about generating a root interface only.
If you want not to generate a other api interfaces, then there should be a separate property (e.g.: apiInterfaceStrategy)

I will introduce a new config apiInterfaceStrategy which will accept two values:

• INTERFACE_PER_OPERATION (default) - Generate separate interface classes for each GraphQL operation.
• DO_NOT_GENERATE - Do not generate separate interfaces classes for GraphQL operation.

Plus, I will add another enum option to apiRootInterfaceStrategy:

• DO_NOT_GENERATE - Do not generate super interface for GraphQL operations.

@jxnu-liguobin I've created a separate issue to track sbt-plugin changes: #276
