    CLOUDSTACK-8715: Add channel to Instances for Qemu Guest Agent

    This commit adds a additional VirtIO channel with the name
    'org.qemu.guest_agent.0' to all Instances.
    
    With the Qemu Guest Agent the Hypervisor gains more control over the Instance if
    these tools are present inside the Instance, for example:
    
    * Power control
    * Flushing filesystems
    * Fetching Network information
    
    In the future this should allow safer snapshots on KVM since we can instruct the
    Instance to flush the filesystems prior to snapshotting the disk.
    
    More information: http://wiki.qemu.org/Features/QAPI/GuestAgent
    
    Keep in mind that on Ubuntu AppArmor still needs to be disabled since the default
    AppArmor profile doesn't allow libvirt to write into /var/lib/libvirt/qemu
    
    This commit does not add any communication methods through API-calls, it merely
    adds the channel to the Instances and installs the Guest Agent in the SSVMs.
