[#10] Make the bootstrap.mlockall setting configurable

Note, the default value of the `mlockall` attribute is `false` [elastic/elasticsearch#567]. However, in production environment, it is _highly_ recommended to run with a `mlockall:true` setting -- thus the cookbook sets it to `true`. If you encounter problems, try running with `mlockall:false`. Closes #10.
