[pbs-devel] [PATCH widget-toolkit v3 07/14] notification: add UI for adding/updating webhook targets

[Lukas Wagner <l.wagner@proxmox.com>]

The widgets for editing the headers/secrets were adapted from
the 'Tag Edit' dialog from PVE's datacenter options.

Apart from that, the new dialog is rather standard. I've decided
to put the http method and url in a single row, mostly to
save space and also to make it analogous to how an actual http request
is structured (VERB URL, followed by headers, followed by the body).

The secrets are a mechanism to store tokens/passwords in the
protected notification config. Secrets are accessible via
templating in the URL, headers and body via {{ secrets.NAME }}.
Secrets can only be set/updated, but not retrieved/displayed.
