This is a serde-based parser for the file format our perl
code read via `PVE::JSONSchema::parse_config`.
This will be used for the node config.
Some support for indexed arrays at the top level is
available but currently commented out and unused as this
is not really compatible with how we write our schemas,
since we store property strings as actual strings using an
object schema as *format* property in the `StringSchema`.
Ideally this could be changed in the future and we can
integrate the serde parsing model more easily without having
to convert between strings manually in the code.

To: pbs-devel
API like in PVE:
GET .../info => current cert information
POST .../custom => upload custom certificate
DELETE .../custom => delete custom certificate
POST .../acme/certificate => order acme certificate
PUT .../acme/certificate => renew expiring acme cert

PVE has 2 domain lists, PMG only 1 since it requires the
additional type.
In PBS I do not want to have 2 lists either, since it seems
rather inconvenient to have 2 different ways to access the
same list.
Currently we decide this based on whether we have multiple
certificate types, which in PBS we don't, so we need a
separate option for this.

Creating the first account gives missing directory

After manually adding it, the HTTP Challenged worked for me.
In the Window "Add: ACME DNS Plugin" choosing (or writing) something in the
dropdown menu DNS API is not possible with only the PBS repositories
configured. It is necessary to install libproxmox-acme-perl from PVE
repositories in addition.
Deleting a certificate shows a confirmation dialog with a truncated message:
"Are you sure you want to remove the certificate used for"
In the window "Register Account" the textfield "Account Name" has the empty
text "default". As far as I know, we use empty texts for real default values.
So this should be removed and get a validator (already in the GUI) instead.
But the API rejects correctly: "parameter verification errors parameter 'name':
parameter is missing and it is not optional."
Registering accounts for both staging and production works. Ordering
certificates with HTTP challenge generally works for both, too. A few times
the HTTP challenge required a manual retry. Maybe we could do something like
increasing timeouts?
I couldn't set up PowerDNS yet & my domains were not fast enough, so finishing
the DNS challenge testing remains todo.
