Apollo-client: Disable console.warn by default

[olalonde]

As a library, it's a bad practice to use console.warn or writing anything to the console by default. It should be possible to disable this behavior.

Use case: I'm using apollo-client to test a graphql API in Node.js and it pollutes my test outputs with unnecessary text.

You can set process.env.NODE_ENV to production, which will suppress all development warnings.

That's not an option as it would break code which assumes process.env.NODE_ENV == "test".
