Bump the allowed HTTP headers in statschannel to 100 [v9.18]
Firefox 90+ apparently sends more than 10 headers, so we need to bump the number to some higher number. Bump it to 100 just to be on a save side, this is for internal use only anyway.
(cherry picked from commit e4654d1a)
Closes #3670 (closed)
