unfortunately, pve-bridge-vid-list allows more than intended. we'd
either need to define a custom type for the lists, or improve the
handling. a `-list` format under the hood calls PVE::Tools::split_list,
which splits on zero bytes if the string contains one, or else on ',',
';' and whitespace.. and at least ';' leads to ifreload not applying the
VLAN settings (with a warning that is very easy to miss, since it
doesn't show up in the task log or task status at all, you only see it
if you run `ifreload -av`!).

two possible solutions:
- use a custom format here, split and call the verify helper from
  pve-common
- use -list here, but map the other delimiters to ' ' either here or in
  pve-common

  side-note: this is basically the "trunks" format, but with a different
  delimiter, couldn't we have a common option/format and just change the
  delimiter based on what we pass it along to?
