[PATCH 05/11] image-account-extension: Add copy-ci-key flag for user

[Uladzimir Bely <ubely@ilbers.de>]

If the flag enabled, CI ssh public key is copied `authorized_keys`
in `$USER/.ssh/` directory.

This allows non-interactive SSH access to the machine with executing
custom commands on the guest VM.
