Description of problem:

When using 'lvs' - if user wants to know the size of i.e.  thin-pool's metadata device - he could ATM use somewhat more complex --select  option to set couple options that needs to match to output resulting value.

We may try to support slightly simpler syntax for this i.e.:

lvs -o  lv_size%metadata  vg/pool

(whathever symbol instead of '%')
will just output size of  metadata LV used for  vg/pool.

It'd very complex to duplicate each LV/SEG field for every condition i.e.
metadata/data/leg/origin or other.

This BZ is rather opening discussion....
