MINOR: cfgparse: support the comma separator on parse_cpu_set

Allow to specify multiple cpu ids/ranges in parse_cpu_set separated by a
comma. This is optional and must be activated by a parameter.

The comma support is disabled for the parsing of the 'cpu-map' config
statement. However, it will be useful to parse files in sysfs when
inspecting the cpus topology for NUMA automatic process binding.
