Fixes #17 Bump openssl version and improve tests

Moves to the 2.x version of the openssl cookbook due to availabilty
issues of the 1.x version. Also improves the kitchen list and tests to
include information about the mariadb version installed.
Fixes #16 Support for MariaDB 10.0 and CentOS 7

This includes support for MariaDB 10.0 on all platforms. At this time we
are using the Fedora 20 packages for CentOS 7 support as there are no
official packages from MariaDB yet (though they are slated for
10.0.14[1]).
