- Configures the maxfile ulimit for the riakcs user.  By default, the
  value is set to 4096
- Adds vim swap files to the git ignores
- Adds .gitignore to ignore vim swap files
- Adds the file_ulimit resource to set the max files ulimit properly on
  CentOS/RHEL,as well as, Ubuntu
- Modifies the stanchion and riak_cs recipes to optionally set the max
  file ulimit using the file_ulimit resource.  By default, the max file
ulimit will _not_ be set.  The ['stanchion']['ulimit']['config_limits']
and ['riak_cs']['ulimit']['config_limits'] attributes control this
behavior.
