Subject: [PATCH] utils/ssh: Only attempt loading ssh keys if no password is
 supplied

In the case of connecting to a system without a password the password
parameter needs to be set to an empty string which will currently still
cause ssh keys to be loaded. Only check for ssh keys when the password
is explicitly set to `None`.
