Cannot request green or noise extra info

[rabidllama]

Here's what I did

Requested a pedestrian route with green and/or noise selected as extra info

url:
https://api.openrouteservice.org/v2/directions/foot-walking/json?api_key=xxx
body:

{
    "preference": "fastest",
    "elevation": true,
    "coordinates": [
        [
            8.683276,
            49.413654
        ],
        [
            8.690014,
            49.402484
        ]
    ],
    "extra_info": [
        "noise"
    ]
}

Here's what I got

An error saying that the extra_info parameter is incorrect.

Here's what I was expecting

To get extra info relating to green and noise

Here's what I think could be improved

It seems the problem lies in there not being the green and noise values added as enum values for ExtraInfo in api/requests/common/APIEnums. Adding them there should fix the problem.
