Library should uppercase HTTP method name #416
Description
I was experimenting with using this library as http client for stripe-php, via psr18-adapter/stripe-php that I'm working on now, but had to go back to Guzzle, as Buzz is broken there. You see, stripe library defines lowercased HTTP methods names everywhere, but their servers do not accept those:
❯ curl -XGET "https://api.stripe.com/v1/customers"
{
"error": {
"message": "You did not provide an API key. You need to provide your API key in the Authorization header, using Bearer auth (e.g. 'Authorization: Bearer YOUR_SECRET_KEY'). See https://stripe.com/docs/api#authentication for details, or we can help at https://support.stripe.com/.",
"type": "invalid_request_error"
}
}
❯ curl -Xget "https://api.stripe.com/v1/customers"

I think you might want to make this library uppercase method names as well, like other libraries do. After all, you do that in some places already
