Even an isolated network has dhcp

[ngyuki]

Fix #500

libvirt's isolated network can have dhcp.

• https://libvirt.org/formatnetwork.html#examplesPrivate

There is no forward element in this case.

@ngyuki I tried locally to run after this change the testacc and they are failing after this PR.

TestAccLibvirtDomain_NetworkInterface
this test namely fails.

Can you try to run: make testacc? https://github.com/dmacvicar/terraform-provider-libvirt/blob/master/CONTRIBUTING.md#running-the-tests-testacc

@ngyuki hi thx for feedback. I will try to test a bit.

can you run on your site the whole testsuite and let me know if you find any errors locally? In travis we skip 2/3 tests

TIA
