[PATCH widget-toolkit 2/2] acme: domain edit: allow setting the alias of DNS domains

[Michal Fox <me@dualfroz.com>]

Domains validated with the DNS challenge can have an alias, so that the
challenge record is created on another domain, which the
'_acme-challenge' record of the domain points to with a CNAME.

But the alias could only be set on the CLI, as the edit window only
kept an existing one in a hidden field. Show it as a text field for
domains with the DNS challenge type, like the plugin.

As a side effect, an existing alias is not kept anymore when switching
a domain to the HTTP challenge type with separate domain entries, like
it is done in Proxmox Mail Gateway, where it has no meaning.

Tested in the browser the same way as the PVE window, both with the
'domains' list (PBS) and with separate domain entries and usage (PMG).
