proxmox: set vxlan-local-tunnelip for loopback interface

Oops. Not sure why stuff apparently worked without it. Especially
switchd on exits which worked itself into a bit of a frenzy.

proxmox: use inner L3 info for ECMP hashing
...
I’m sure I saw fib_multipath_hash_policy=2 (or =1 from last commit)
actually working once, but cannot reproduce. Maybe revisit this at
some point.

proxmox: set up firewall
...
Firewall policy is set in NetBox as cluster services¹. For Proxmox we
have to manually allow communication between nodes when using L3,
since the default management ipset does not get populated correctly.
We also need to open VTEP communication between nodes, which the
default rules don’t. We allow all inter-node traffic, as SSH without
passwords must be permitted anyway.
This also adds some helper filters that are spectacularly annoying to
implement purely in templates.
¹ There is actually no such thing as as a cluster service (yet?), so
instead we create a fake VM for the cluster, define services for it,
and then add the same services to a custom field on the cluster.
Alternative would be to tie services to a specific node, but that
could be problematic if that node is replaced.

proxmox: use multiple non-VLAN-aware bridges
...
The Proxmox SDN feature does not play nice with our FRR and VXLAN setup.
With a single bridge we can’t have interface aliases. So use a bridge
for each VLAN. Actually don’t even have VLANs, just bridges mainlined
into VXLAN tunnels.
Read the list of VLANs carried by Proxmox nodes from a custom field on
the cluster in NetBox. Remove the vmbr0 device from individual nodes.
