1.2.0

• Add mod_proxy_fcgi and mod_fastcgi configuration for Apache (Debian 9 doesn't provide mod_fastcgi anymore; using ifmodule-directive for automatic configuration switching)

• Added tests to ensure /dev/null and /dev/zero are writeable
• Removed postfix hostname (is sometimes injected via installation)
• Fixed smaller bugs
• Fixed bin/console docker:exec command execution
• Updated gems for serverspec
