rbf100{1,2}: set vm.overcommit_memory = 1, per redis requirements
Fixes:
# WARNING overcommit_memory is set to 0! Background
save may fail under low memory condition. To fix this issue add
'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the
command 'sysctl vm.overcommit_memory=1' for this to take effect.
