Add support for profiles, fix tests (#881)

* Fix execute permissions for dns scripts
* Send the profile with the order request
* Update chown command for all alpine based Dockerfiles
* Rewrote the profiles parsing code to be more generic and more readable
* Change some tests which depend on DNS to be warning instead of failure to prevent false alerts
* Skip some ftp tests on centos6 and centos7, setup issue with vsftpd
