CA-121385 Allow creation of VLAN 0 in XenCenter. This applies to the New Network Wizard and the Network Properties.

- The VLAN can be set to 0 only for Creedence or greater hosts on the vSwitch backend.
- When VLAN 0 is selected, an info is shown next to the control, saying "VLAN 0 will receive all traffic not on any other VLAN"
- Also fixed an error on New Network Wizard, where the "VLAN in use" message was still visible when changing the NIC.

CP-8474: Remove iSL radio button from XenCenter for >= Creedence servers.
Made the radio button invisible for Creedence or higher XS hosts.
Removed previous StorageLink-related upgrade pre-checks and added (strict) check to prevent upgrade when StorageLink is used.
