Add repo sub command

- Add `repo` sub command.
- Show repo basic info as the inital functionality.
- Use the GH graphql api.
- Add `graphql_client` crate.
- Add `graphql` queries directory in the root with the basic_info query.
- Include files generated using `graphql-client` CLI.
   This need to be part of a `build.rs` for later.
