upstream commit

Add an AddKeysToAgent client option which can be set to
 'yes', 'no', 'ask', or 'confirm', and defaults to 'no'.  When enabled, a
 private key that is used during authentication will be added to ssh-agent if
 it is running (with confirmation enabled if set to 'confirm').

Initial version from Joachim Schipper many years ago.
