[pbs-devel] [PATCH proxmox-backup] api2/types: fix DNS_NAME Regexes

[Dominik Csapak]

We forgot to put braces around the DNS_NAME regex, and in
DNS_NAME_OR_IP_REGEX

this is wrong because the regex

 ^foo|bar$

matches 'foo' at the beginning and 'bar' at the end, so either

 foobaz
 bazbar

would match. only

 ^(foo|bar)$

 matches only 'foo' and 'bar'
