CLOUDSTACK-9362: Skip VXLANs when rewriting the bridge name for migrations
From the [JIRA
issue](https://issues.apache.org/jira/browse/CLOUDSTACK-9362):
>
https://github.com/apache/cloudstack/commit/bb8f7c652e42caacff5adce1ce60342603677605
>
> The above commit introduces rewriting of bridge device names when
migrating a virtual machine from one host to another. However, it also matches
bridges called "brvx-1234" and rewrites them to (in my case) "brem1-1234" -
this doesn't match the bridge name on the destination and causes the migration
to fail with the error:
>
> error : virNetDevGetMTU:397 : Cannot get interface MTU on 'brem1-1234':
No such device
>
> I have flagged this as major because it's not possible to migrate VMs
using VXLANs for maintenance, which seems important (it's certainly important
to me!).
