Feature request: Create record if it does not exist

[qdm12]

1. What's the feature?

   Instead of simply updating a record, create it if it does not exist. Done for:

   • [x] Cloudflare
   • [x] Digital Ocean
   • [x] ~Don Dominio~ - not possible, see https://github.com/qdm12/ddns-updater/issues/533#issuecomment-1914153109
   • [x] Linode
   • [x] OVH - api mode
   • [x] Gandi
   • [x] Strato
   • [x] Porkbun
   • [x] Azure
   • [x] ChangeIP - not possible

2. Why do you need this feature?

   • Easier to manage your DNS without creating a record for each host.

3. Extra information?

Refers to #110

Strato.de will set an A record at creation of a domain/subdomain. So there is no need to create one for Strato.de services.

I included to the list

• [x] OVH
• [x] Gandi

I double-checked for Gandi and the record is created when it does not exist. For OVH I only checked when mode is "api"

+1 on this one! Cloudflare does not create new records (using Global Key), but it refreshes them if manually added on CF
