WIP: Initial check-in for install instructions [ci skip]

Let's get these into version control first and iterate on them

If everything needs sudo would it be simpler to sudo su as the first step? Likely will make it easier to copy paste.

st2-register-content and st2 CLI commands don't require sudo. Explicitly calling out the steps that really need sudo seems better to me. Anyways, this can be changed later. I was trying to validate #76 and without RHEL instructions, I wasted 30 mins to get to a bare st2 install. Also found couple of issues. So intent is to get things into version control first and iterate on packages and instructions.

[lakshmi-kannan]

Should be then same for el6/el7 wget -qO - "https://setup.ius.io/" | sudo bash -s.
To make it more generic.
