Non-breaking change: club matches endpoint

As of 8th of March, we will start to trim the list of finished matches for endpoint /pub/club/{ID}/matches to the most recent 1000, for performance reasons.

Response will still contain the full list of "registered" and "in_progress" tournament matches.
The new field in the response: "comment", will contain a hint in case the results were trimmed.

{
    "finished": [ 1000 most recent matches ],
    "in_progress": [ All in progress matches ],
    "registered": [ All registered matches],
    "comment": "Results are temporarily reduced to the most recent 1000 matches for performance reasons"
}
