This patch adds new action called list_pools. It has two modes of execution, non-verbose and verbose. Non verbose, executed just with "lnst-ctl list_pools" command, prints out pool names and their paths in pool_name=/path/to/pool format.

For verbose mode, option -v or --verbose must be entered. It prints pool names and their paths and in addition, it lists through all slave machine config files in pool directories and prints their contents in more human readable format.

Pools are acquired from all the configs lnst-ctl would use in normal run.

list_pools action can be combined with --pools argument in both verbose and nonverbose mode so you can filter the output as you wish.

list_pools action replaces --dump-pools option

changes in v4: * mentioned that list_pools action replaces --dump-pools option * used SlavePool object with new get method for getting pools instead of calling private methods * reorganized patchset so adding get_pools is first * added spaces before and after + sign * renamed network to label to be constistent with XMLs * warn user when pool directory does not exist
