I realized that ContentTooLargeException can't simply extend HttpStatusException because HttpStatusException is in server package but ContentTooLargeException is in common.

I think my first idea was wrong, sorry. This issue should be considered in Armeria 2.0. Would you mind closing this PR and looking at other issues?
