Make cluster dashboard KUKSA.val server configurable
Add CLUSTER_DEMO_VISS_HOSTNAME variables to the cluster-dashboard and flutter-cluster-dashboard recipes and tweak the installed configuration files to use the address it specifies. This provides a hook for tweaking the configuration for e.g. running in the guest VMs in the QEMU+KVM demo. This may need to be tweaked down the road to use something like multiple packages + the alternatives mechanism instead. Bug-AGL: SPEC-4618 Change-Id: I101b2c966fc2923a5f4946ea1c5e95695061c041 Signed-off-by: Scott Murray <scott.murray@konsulko.com>
