Sharing fragments

[minhthong095]

Sharing fragment between queries and schemas.

This feature only enable if developer declare input fragments_glob like those configuration. If it isn't declared, Artemis will turn back to original.

Will work well if it is declared within queries_glob defined on directly path.

Good

- schema: pokemon.schema.json
  queries_glob: graphql/a.graphql
  output: lib/graphql/a.dart
- schema: pokemon.schema.json
  queries_glob: graphql/b.graphql
  output: lib/graphql/b.dart

Failed

- schema: pokemon.schema.json
  queries_glob: graphql/*.graphql
  output: lib/graphql/common.dart

Because in original source, even if i have 2 fragments with same name, add_query_prefix: true in 2 different files, different query (operation) name and build.yaml config like 'Failed' above. Artemis will not generate too.

So i came up with that solution.

In a huge project my team working on it's convenient to use sharing fragments.

Already considered this issue: #52

I think it's good if we can add a working fragment example.

Hey there @minhthong095! First of all, thanks for this PR.

Although I still think the proper approach to this enhancement would be to have middlewares, I was unable to fully work on it yet, so this PR would be the best solution for this for the time being.

However, we need to have tests (and examples) of how to use this new configuration, along with proper changes on documentation.

Could you do those changes? Ping me if you need any help!

Hi @comigor , I implemented test, examples and correct little code in fragment_query.dart and fragment_query.query.graphql for suitable with this feature. Let me know if i need to do something else. Thanks
