[pbs-devel] [PATCH proxmox v2] fix #3302: allow for more characters for email

change to something similar as in pve-common
word characters, +, -, ~ and . for the local part

and refactor it in a const_regex for reuse

note that we cannot use the regex in the api yet, as that would be a
breaking API change (we use a much more relaxed regex for a users email),
but we should do that for 2.0
