Add ons - Axiom.co integration

One thing that I feel is really missing on Qovery at this point is a logs analytics dashboard; we're mostly blind on what's happening on the cluster, and that's the kind of thing that's not easy to implement if you don't want to mess with the platform you're running on. IIRC native Grafana and Datadog integrations have been proposed already but the first may be complicated to implement and maintain for you, and the second is known to be pretty expensive. Axiom may be a good middle ground that may be both easy for you to integrate and affordable for most of your clients. They're part of Crane's portfolio so I guess it should be easy for you to speak with them and it would probably make a lot of sense in business terms. :)
