Control the number of bridges included in each test
We have the following line to limit the number of bridges requested for each test:
// The maximum amount of bridges per batch. MaxBridgesPerReq = 100
but, each test batches together all of the bridges in a request. This means that if a user actually requests to test 50 or 100 bridges, we include 50-100 bridges in the
SETCONF line sent to tor.
