Subject: ssh: T3789: add custom validator for base64 encoded CLI data

SSH keys used for remote login are supplied as base64 encoded data on the CLI.
The key is not validated, thus an invalid copy/pasted key will render the login
useless. This commit adds a custom and re-usable validator which check if the
data is properly base64 encoded.
