Subject: [PATCH 21/33] tests: Add testing for lvmlockd failure

After the lvmlockd abnormally exits and relaunch the daemon, if LVM
commands continue to run, lvmlockd and the backend lock manager (e.g.
sanlock lock manager or IDM lock manager) should can continue to serve
the requests from LVM commands.

This patch adds a test to emulate lvmlockd failure, and verify the LVM
commands after lvmlockd recovers back.  Below is an example for testing
the case:

  # make check_lvmlockd_idm \
	LVM_TEST_BACKING_DEVICE=/dev/sdo3,/dev/sdp3,/dev/sdp4 \
	LVM_TEST_FAILURE=1 T=lvmlockd_failure.sh
