CLOUDSTACK-771: maven: add mysql version reference to enable non-snapshot builds

If you update your build to build a version with a name not ending in -SNAPSHOT,
you are required to declare versions on all your depdendencies. There is already
a cs.mysql.version property, this patch makes sure it is used where appropriate.
