tools: add --binary arg to pvs,vgs,lvs and {pv,vg,lv}display -C and report/binary_values_as_numeric lvm.conf option

Browse Source 
The --binary option, if used, causes all the binary values reported
in reporting commands to be displayed as "0" or "1" instead of descriptive
literal values (value "unknown" is still used for values that could not be
determined).

Also, add report/binary_values_as_numeric lvm.conf option with the same
functionality as the --binary option (the --binary option prevails
if both --binary cmd option and report/binary_values_as_numeric lvm.conf
option is used at the same time). The report/binary_values_as_numeric is
also profilable.

This makes it easier to use and check lvm reporting command output in scripts.
