use symfony/contracts instead of guzzle (documentation)

[tacman]

composer require dunglas/digital-ocean-bundle symfony/http-client nyholm/psr7 guzzlehttp/promises

Symfony now supports its own version of promises/contracts, since this is a Symfony bundle, what would be the way to insall without guzzle?

I've never quite grasped the psr-18 interface and how that relates to contracts, but I always appreciate it when a bundle allows me to install my own client, mostly because having the Symfony HttpClient calls available in the debug toolbar makes debugging so much easier.

I'm pretty sure there's a way to install this without guzzle promises.
