traffic_replay: Add a max-members option to cap group size
traffic_replay tries to distribute the users among the groups in a
realistic manner - some groups will have almost all users in them.
However, this becomes a problem when testing a really large database,
e.g. we may want 100K users, but no more than 5K users in each group.
This patch adds a max-member option so we can limit how big the groups
actually get.
If we detect that a group exceeds the max-members, we reset the group's
probability (of getting selected) to zero, and then recalculate the
cumulative distribution. The means that the group should no longer get
selected by generate_random_membership(). (Note we can't completely
remove the group from the list because that changes the
list-index-to-group-ID mapping).
