suite: vm-instance cloud-init network-data for netplan guests (netplanDhcp)

# A netplan guest configures only the interface cloud-init's fallback covers and
# keeps none of the DHCP-supplied search domains, so the assertions below are on
# the two properties that change that: every ethernet asks for DHCP, and the
# link keeps the domains it is offered. Naming an interface instead of matching
# a glob would satisfy a field assertion and still leave a guest whose NICs
# enumerate differently unconfigured, which is why the match stanza is asserted
# rather than the presence of the key.
