some tests left dangling bg processes originating in lvm2 commands being able to spawn any bg polling process (lvchange, vgchange, pvmove, lvconvert...) Initial fn 'add_to_kill_list' should collect processes with specific parameters (proc's command line and parent processes ID). After testing finishes the fn kill_listed_processes should remove these listed by 'add_to_kill_list'. Unfortunately it proved to be prone to an error especially in scenarios where cmd line of initiating command contained characters required to be espaced before passing to shell script to make it work correctly. (Or if cmd spawned more than one bg process with same cmd line. i.e.: vgchange or lvchange). The new implementation is much simpler. It uses env. variable (LVM_TEST_TAG) for marking a process desired to be killed later or during test env. teardown. (i.e.: LVM_TEST_TAG=kill_me_$PREFIX to kill only processes related to current test environment)
