I merged "quickstart" doc with "ansible-deployment" and "deploy-all-in-one-node". All three of them was covering same topic and added a lot of confusion for new users. I added some clarification lines from myself, with main goal to recive one straightforward document for new users. Change-Id: I793244c47ffbe0ba304e79bacf708494e59d99c4
