Provide 429 exception for webhook updates on inline query

[chaslain]

When several users are active on my bot at one time, mostly interacting with callback queries, I am getting a 429 error sending the update back.
I believe if my bot is receiving one callback query, a 1:1 ratio of requests in to requests out should not trigger the 429 rate limiter, especially in reference to the same inline message id, as this cannot be used to spam.

You can call answerCallbackQuery without any limits, editing of the message in question is still subject to per chat limits.
