The function that cpu-map uses to parse CPU sets, parse_cpu_set(), was
etended in 2.4 with commit a808235 ("MINOR: cfgparse: support the
comma separator on parse_cpu_set") to support commas between ranges.
But since it was quite late in the development cycle, by then it was
decided not to add a last-minute surprise and not to magically support
commas in cpu-map, hence the "comma_allowed" argument.

Since then we know that it was not the best choice, because the comma
is silently ignored in the cpu-map syntax, causing all sorts of
surprises in field with threads running on a single node for example.
In addition it's quite common to copy-paste a taskset line and put it
directly into the haproxy configuration.

This commit relaxes this rule an finally allows cpu-map to support
commas between ranges. It simply consists in removing the comma_allowed
argument in the parse_cpu_set() function. The doc was updated to
reflect this.
