Property AddKeysToAgent
AddKeysToAgent
AddKeysToAgent: when not null, a key loaded from an identity file that the server accepts is added to the agent with these
constraints (yes; confirm asks for each use; a time interval sets the lifetime). Null for no (the default) and
for ask, which needs a prompt this library does not show.
