qga: Disable unsupported commands by default

Currently management softwares cannot know whether a qemu-ga command is
supported or not on the running platform until they actually execute it.
This patch disables unsupported commands at launch time of qemu-ga, so that
management softwares can check whether they are supported from 'enabled'
property of the result from 'guest-info' command.
