Willy Tarreau 0e875cf291 MEDIUM: listener: switch the default sharding to by-group 
Sharding by-group is exactly identical to by-process for a single
group, and will use the same number of file descriptors for more than
one group, while significantly lowering the kernel's locking overhead.

Now that all special listeners (cli, peers) are properly handled, and
that support for SO_REUSEPORT is detected at runtime per protocol, there
should be no more reason for now switching to by-group by default.

That's what this patch does. It does only this and nothing else so that
it's easy to revert, should any issue be raised.

Testing on an AMD EPYC 74F3 featuring 24 cores and 48 threads distributed
into 8 core complexes of 3 cores each, shows that configuring 8 groups
(one per CCX) is sufficient to simply double the forwarded connection
rate from 112k to 214k/s, reducing kernel locking from 71 to 55%.
