Remove Paramiko Dependency

[m3nu]

This is a heavy depdency and we only use it to verify a file is a SSH key. Would favor removing it and just checking files for starting with -----BEGIN OPENSSH PRIVATE KEY-----.

And check for common SSH issues, like wrong ownership or permissions.

Nice. So this confirms the first line. Then I'd just use that to verify the file and not show the key format (doesn't add much value). Most users will just keep it on Default anyways. Algo to populate the dropdown would be like this:

1. Grab files in ~/.ssh
2. Ignore config and known_hosts*. And *.pub
3. For other files read first line.
4. If it matches, show the filename in dropdown.

Right?
