Enable tox use of site-packages for libvirt.

Enable the use of site-packages in tox which will allow the use of the
system install of libvirt while testing.

Hardcode the libvirt host UUID for tests that check this UUID when
system libvirt is being used. Without this hardcoding eight tests
would fail when using the system libvirt install.

Partially fixes bug #1113181

Change type of ssh_port option from Str to Int

The type of CONF option virtual_power_ssh_port was incorrectly defaulted
to Str. This can cause Paramiko to raise when casting to %d.

Fixes bug 1157824.

Don't actually connect to libvirtd in unit tests.

The libvirt tests shouldn't actually be connecting to libvirtd
while running unit tests. Many of the tests were calling either
getLibVersion or getCapabilites, which would start a connection.
Fake these out so the tests can run properly without libvirtd.

Fixes bug 1157992
