Naming conventions for GraphQL schema

The "Naming Convention" feature in GraphQL schema allows users to customize the names of fields, types, and arguments. This is particularly useful when dealing with multiple databases within a Hasura application. There are two available naming conventions - hasura-default and graphql-default. By default, all Hasura applications use the hasura-default naming convention, which uses snake casing for names and does not change enum values. The graphql-default naming convention uses PascalCase for type names, camelCase for field names and arguments, and UPPERCASE for enum values. Users can also customize root fields and type names by adding prefixes or suffixes.
