fix(allocation): maxMatches limit to 100

Some games might choose to run larger pod resources and increase number
of matches running in each room/instance, thus increasing from 30 to 100.
The limit in the max matches is useful so configuration stays in a sane
number to help in autoscaling and roundings.
