Problem / Steps to reproduce

When using identity_file on sake.yaml, sake ssh won't use the identity file.

Content of sake.yaml:

disable_verify_host: true

servers:
  srv1:
    host: x.x.x.x
    user: root
    identity_file: private.pem

Running sake ssh srv1 will result in failed authentication, while sake run ping -s srv1 is OK.

sake ssh srv1
root@x.x.x.x: Permission denied (publickey).

sake run ping -s srv1
