Title: Pass SSH identity file option to Knife::Server::SSH

This fixes authentication errors when using the `--identity-file` option with bootstrap commands. If no option is given, an array containing `nil` will be passed as the list of private keys to try and Net::SSH seems to handle that correctly.
