VMware: remove duplicate key from test_instance dict

Remove the duplicate 'node' key from test_instance dict

Change-Id: I1199b5f9428f3fad196bd10331b268f9a3eddcf9
change the firewall debugging for clarity

When we are building rules ensure we log the instance['id'] so
we can actually correlate the iptables output to UUID for the
instance.

Also bundle up the security group to iptables translation to a
final view of the world instead of the piecemeal rule at a time
view.

Display what rules are being skipped in the add process, as the
skips seem to happen a lot. If this is completely normal we should
probably delete the bit entirely at some later point.
