Multiple properties are related to system installed inside the VM, so it
makes sense to have them the same for all the VMs based on the same
template. Modify default value getter to first try get the value from a
template (if any) and only if it fails, fallback to original default
value.
This change is made to those properties:
- default_user (it was already this way)
- kernel
- kernelopts
- maxmem
- memory
- qrexec_timeout
- vcpus
- virt_mode
This is especially useful for manually installed templates (like
Windows).
Related to QubesOS/qubes-issues#3585
Use VM's actual IP address as a gateway for other VMs, instead of
hardcoded link-local address. This is important for sys-net generated
ICMP diagnostics packets - those must _not_ have link-local source
address, otherwise wouldn't be properly forwarded back to the right VM.
Human readable format `str(datetime.datetime)` is a nightmare for Admin
API level communication. Especially setting the property in a format
that it was read was not supported, and handling such format in
untrusted input handling code is a bad idea. Revert to a simple intiger
format.
When dom0 do not provide the kernel, it should also not set kernel
command line in libvirt config. Otherwise qemu in stubdom fails to start
because it get -append option without -kernel, which is illegal
configuration.

1. It is unclear yet whether dispvm_netvm will be implemented in core3, but
probably not.
2. Remove tests for setting memory/cpu above host resouces - rejecting
those values at property set time would break backup restore on some
machines (when migrating from bigger to smaller system).
Since qvm-prefs is now a generic tool without any property-specific
stuff, we can tests properties getters/setters in QubesVM class unit
tests.
Now most of properties are tested. Some of those tests still fails
because missing/incomplete underlying implementation.
