Erlang cookie is visible by ps command

[norton]

Hibari's erlang cookie is stored in the vm.args configuration file. This file is given as an argument to erl as -arg_file. Unfortunately, this file is not read by the beam.smp process directly but passed as command line arguments that are visible by the ps command.

I'd prefer to use the ~/.erlang.cookie approach to provide a little bit more security over the current behavior. This issue is common to rebar and it's default templates (e.g. nodetool).
