Add clustermgtd heartbeat path to resume and suspend program configs

* Add clustermgtd heartbeat file path to resume program and suspend program config, so cloud bursting program can have logic to prevent cluster usage when clustermgtd is down
* Change permission of /opt/slurm/etc/pcluster/.slurm_plugin from 0644 to 0755 so files in the directory can be listed and read
