Hibari and Linux vm.swappiness=0 #2

An explicit note in the installation README and appropriate documentation guides should be added for Linux deployments. The vm.swappiness setting should be set to zero.

Swapping is not a good feature for a running Erlang virtual machine.

It seems recent Linux kernel has changed the behavior when vm.swappiness is set to 0. It no longer uses the swap space even though it runs out RAM.

Suggest vm.swappiness = 1 instead.
