improved gql-cli script

[leszekhanusz]

Breaking changes:

• Now printing result as json
• Now working with multi-lines queries, using Ctrl-D (EOF) to execute queries
• Using --variables instead of --params

Improvements of the gql-cli script:

• add --version flag
• add --verbose and --debug arguments
• add --operation-name argument
• add --headers argument
• examples added in --help
• moved most of the script content in the gql module
• added sphinx docs, usage automagically set using sphinx-argparse
• added tests for the gql-cli script

Still need to add tests for the script code coverage

[KingDarBoja]

Besides getting no output while testing on my conda environment, I see the other arguments working (like help, debug, verbose). Need some time to checkout what's the correct usage on my case but overall looks great!

EDIT Finally:

$ echo query { continent(code:"AF") { name } } | python scripts/gql-cli https://countries.trevorblades.com
{"continent": {"name": "Africa"}}
// Some error related to asyncio issues with windows
