[Module] Let's Encrypt

[Bizarrus]

This is only for Wildcards!
The domain must be managed by Sentora's DNS, otherwise the plugin cant manage the _acme-challenges of the domain for validation.External Nameservers are not supported, because when the wildcard certificate will be requested, you must add cryptographic tokens as an TXT record. Thats not possible on external DNS. A manual update by the user will break the process and generates much of overhead, because the script must wait if the TXT records available - See here: https://github.com/skoerfgen/ACMECert/is...-475924357

By default, the Nameserver configuration for Sentora's DNS ist n1./ns2.$domain.
