 We should rethink the value of `INTRO_POINT_LIFETIME_INTRODUCTIONS` set to
 `16384` right now.

 An attacker can intentionally hit that limit faster than the normal
 lifetime of intro points (18 to 24 hours) thus triggering an IP rotation
 which can lead to popularity leak or maybe other bad possible issues.

 It's also possible that it's too small for busy hidden service thus
 increasing it to fit busy HS.
