Update scripts

Managed to deploy this today :) https://176.58.116.34/instructions
This is an attempt to extract some deployment and production provisioning configuration, not ideal but a start. 

- [x] docker:
  *  had to [add `rootflags=nobarrier`](https://github.com/fgrehm/vagrant-lxc/wiki/Usage-on-Linode#configuring-grub)  to GRUB get Docker working with AUFS on Linode (using pv-grub).
- [x] default http in production
- [x] production / deployment env in bash 
- [x] remove .ruby-gemset
- [x] remove redundant echo statements
