Subject: Added new method for wallet-backend, update

update will work generally like get, but only for objects that have a
concept of updating content automatically, like keytabs and passwords.
For these, the content will be updated before sending to the client.

In a later release get for keytabs will be modified to never update the
kvno before sending to the user, and so the unchanging flag will be
phased out in lieu of explicitly using the method that does what you
want.
