make sane defaults for MySQL settings

In dev environments, there is no /etc/cloudstack/management/db.properties file
That forces you to specify all parameters on the command line. This commit
sets some defaults, like port 3306, user root and localhost.

When available, it will still get settings from the config file and it will
also allow you to override it on the command line. So it is fully backwards
compatible.
