Bug Description

This is a follow up of https://bugs.launchpad.net/fuel/+bug/1413702

As of LP #1413702, vm.swappiness=10 is now configured only on controller nodes. This bug is created to look into the possibility of configuring this value by default on *all* nodes, regardless of the role on MOS 8.0.

Steps to reproduce:
"cat /proc/sys/vm/swappiness" on controllers shows 10. All other nodes show 60.

Expected Results:
vm.swappiness=10 on all nodes

Actual Result:
vm.swappiness=10 on controller nodes
vm.swappiness=60 on all other nodes

Reproducibility:
N/A

Workaround:
Manually configure vm.swappiness=10 on all nodes

Impact:
N/A
