Keep metadata around in decrypted version so that file can be re-encrypted with same settings

[mitar]

I would suggest an option to keep metadata around in decrypted version of the YAML file so that file can be re-encrypted with same settings, without having to have .sops.yml file around. So I could send encrypted file to a friend, they could decrypt it, change things, and encrypt it back. With all metadata for both operations in the file.

Storing it in the decrypted file doesn't sound like a good idea to me, but having a way to create a config file from an encrypted file would make sense.
