Add basic ansible playbook to setup/secure a ubuntu instance

[theskumar]

This is done when:

• [ ] there is common role that upgrade/update instance, setup fail2ban, utf encoding, server time, setup www-data roles, etc.
• [ ] Travis CI server configuration is added with proper private keys and environment variable
• [ ] there is a vargrant setup to run that ansible script, need further documentation (#2, #5)
• [ ] README.md update with all the things need to run the setup locally and instructions on how the deployment works via travis.
