MINOR: bind-conf: support a new shards value: "by-group"
Setting "shards by-group" will create one shard per thread group. This
can often be a reasonable tradeoff between a single one that can be
suboptimal on CPUs with many cores, and too many that will eat a lot
of file descriptors. It was shown to provide good results on a 224
thread machine, with a distribution that was even smoother than the
system's since here it can take into account the number of connections
per thread in the group. Depending on how popular it becomes, it could
even become the default setting in a future version.
