Add variables to the proxy

This PR adds the capability of handling variables to the proxy.
Variable definitions will get parsed and printed as well as proxied to the backend.
Variables defined in the request JSON will be proxied to the backend too.

Thanks to @mvid for contributing this feature!

v1.4.0

This release adds the "staticProxy" cmd.
Static proxy is a ready to use configurable proxy.
The proxy (currently) works with a single backend.
In the current version it comes with 2 features:

1. Validation (validates queries against a schema)
2. Context Middleware (rewrite query Arguments based on request headers)

The lexer now supports an input up to 1.000.000 Byte. (Could be configured to more, would increase memory usage).

I've removed a few bottlenecks so that the proxy is able to parse 500kb schema's on a modern CPU in < 10ms. Small schemas (<50kb) can be parsed in <1ms. Query parsing and validation is usually <1ms.
This makes the library/proxy a good fit if the schema is not known ahead of time. So it's definitely possible to fetch the schema at request time, parse it and then proceed with the request.

v1.3.0

This version adds initial support to build a graphql proxy. To illustrate possible use cases a context based middleware was added. It's intended to rewrite graphql queries based on the request context in combination with schema annotations via directives.
