Add the possibility to transfer GPG and SSH keys from previous installs

[axurright]

describe the request

A very weird idea, but I think archinstall could have a feature where you can connect to an old install, to import files that you can't transfer through other means, like, GPG of SSH keys.

Do you mean like archinstall --conf previous_install.json? :)

[axurright]

Something like that, but with the option to also send GPG and SSH keys.

[Torxed]

Ah, are you saying that before installing over a system — we should extract SSH and GPG keys and then re-insert them into the new system?

If so I think I understand better now hehe

[axurright]

I'll rename this accordingly
