Title: Translate device mapper numbers to names.

Hello and thank you for tcollector,
For iostat.py, for device mapper devices, instead of a number:
dev=dm-6
it would be the name:
dev=a-free-man

Any additions or changes to entries under /dev/mapper would require the collector to be restarted in order to pick up the mapping from device mapper number to name.

Thanks.
