Deploy tests in gluu digital-ocean and document step by step

[christian-hawk]

Right now tests are being runned in @christian-hawk digital ocean cloud.

Waiting till "destroy droplets script" be done (#21) so we can fully automate the cloud droplets with the lowest cost possible (create droplet -> run tests -> destroy droplets)

We need to have a digital ocean api token, and we will:

• create droplet and setup idp/op with test data
• snapshot idp/op
• create droplet with init scripts to install gluu and passport testing branch
• snapshot droplet with init scripts
• destroy droplets
• setup tests
• setup jenkins (temporary running in testing instance)
• run tests

I redirected my dns t1.techno24x7.com to gluu's DO floating IP, later we can change hostname
