The current default behavior for VirtIO network devices is to default to 1500
MTU, unless otherwise specified. This is inconvenient in cases where the MTU is
not the default value (e.g. for VXLAN VNets or bridges with jumbo frames).
Containers already inherit the MTU of the bridge, if not set, so change the
behavior of VMs to be more in line with containers. This also makes using
non-standard MTUs more convenient and less error-prone since users do not have
to remember setting the MTU everytime they configure a network device on such a
brige.

Changes from v1:
* better document this behavior
* show better hints in the UI
* improve test case
