Feature request to backup and restore config

Describe the solution you'd like

I would like to be able to backup my Nginx Proxy Manager configuration via the web interface, receive a file (tar.gz?) that I can then use to restore via the web interface to a fresh instance of Nginx Proxy Manager.

Describe alternatives you've considered

I appreciate I can backup the /data and /letsencrypt folders and copy these manually, but a simple web interface would make this process easier.

Additional context

My imagined process would be: Go to settings-> Click "Back Up Configuration", receive tar.gz file.
On new machine/instance: Go to settings-> Click "Restore Configuration", upload tar.gz file, warning all existing config will be overwritten, agree, all hosts, access lists, certs, users/passwords etc are restored and active

Start by reviewing the settings web interface and how the /data and /letsencrypt folders are currently handled. Define the archive contents, upload and overwrite warning flow, and restoration of hosts, access lists, certificates, users, and passwords; done means backup and restore work through the web interface on a fresh instance.
