Ability to ignore NS check for DNS Provider changes

[d19dotca]

It'd be amazing if we could have the option in Cloudron to ignore the nameserver checks for DNS Providers when we want to change the DNS Provider for a domain.

This stems from a discussion I raised a year ago here: https://forum.cloudron.io/post/31357

I'm hoping that Cloudron can be configured with a checkbox or option to disable name server checks so that we can then use Cloudron to proactively setup the DNS records at the new DNS Provider before we make the final switch on the registrar. This will allow us to switch DNS Providers in Cloudron without downtime for users of the affected domain.

Please consider this feature request for inclusion in Cloudron. Thank you so much.
