Subject: [PATCH 26/33] tests: multi-hosts: Add VG testing

This patch is to add VG testing on multi hosts.  There have two scripts,
the script multi_hosts_vg_hosta.sh is used to create VGs on one host,
and the second script multi_hosts_vg_hostb.sh afterwards will acquire
global lock and VG lock, and remove VGs.  The testing flow verifies the
locking operations between two hosts with lvmlockd and the backend
locking manager.

  On the host A:
    make check_lvmlockd_idm \
      LVM_TEST_BACKING_DEVICE=/dev/sdj3,/dev/sdk3,/dev/sdl3 \
      LVM_TEST_MULTI_HOST=1 T=multi_hosts_vg_hosta.sh

  On the host B:
    make check_lvmlockd_idm \
      LVM_TEST_BACKING_DEVICE=/dev/sdj3,/dev/sdk3,/dev/sdl3 \
      LVM_TEST_MULTI_HOST=1 T=multi_hosts_vg_hostb.sh
