James O. D. Hunt f3e454560e docs: Change install guides to use bash code blocks 
Change the installation guides so that all commands the user must type
use an explicit bash code block rather than a standard code block.

This adds meaning to the documents and will then allow us to extract
the commands and run them for testing purposes.

Fixes #92.

Installing Kata Containers on Ubuntu

Note: Kata Containers is available for Ubuntu* 16.04 and 17.10. Currently Kata Containers is currently only build for x86_64.

This step is only required in case Docker is not installed on the system.

  1. Install the latest version of Docker with the following commands:
$ sudo -E apt-get -y install apt-transport-https ca-certificates wget software-properties-common
$ curl -sL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
$ arch=$(dpkg --print-architecture)
$ sudo -E add-apt-repository "deb [arch=${arch}] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
$ sudo -E apt-get update
$ sudo -E apt-get -y install docker-ce

For more information on installing Docker please refer to the Docker Guide

$ curl -sL  https://download.opensuse.org/repositories/home:/katacontainers:/release/xUbuntu_$(lsb_release -rs)/Release.key | sudo apt-key add -
$ sudo -E apt-get update
