Note that this is the first part of the support. A second part involves dealing with the package names. Among the changes: - add several functions to determine some distro-specific behavior (how to call usermod, if some features are available on the distro, etc.) - correctly detect openSUSE and SLE in GetOSVersion, and set DISTRO accordingly - new is_suse() function to check if running on a SUSE-based distro - use zypper to install packages - adapt apache virtual host configuration for openSUSE - some simple fixes (path to pip, mysql service name) Change-Id: Id2f7c9e18a1c4a7b7cea262ea7959d183e4b0cf0
