Saravanan KR e9a2fdc0af Disable exit on error for pacemaker commands for update flow
Package update fails on compute node, when yum_update checks for
pacemaker status via systemctl command. Because exit on error (-e)
option has been enabled recently, this issue is happening. Fixing
by, executing the command only on nodes where pacemaker is enabled.
Closes-Bug: #1668266
