Support Let's Encrypt Profile in New Order

[campersau]

Let's Encrypt added a new "profile" parameter to the "new-order" endpoint. It would be great if this could be added here as well.
E.g. "profile": "tlsserver"

Full example:

POST /acme/new-order HTTP/1.1
Host: example.com
Content-Type: application/jose+json

{
    "protected": base64url(...),
    "payload": base64url({
        "profile": "tlsserver",
        "identifiers": [
            { "type": "dns", "value": "www.example.org" },
            { "type": "dns", "value": "example.org" }
        ],
    }),
    "signature": "H6ZXtGjTZyUnPeKn...wEA4TklBdh3e454g"
}
