usermanager, mod_auth_*: Add get_account_info() returning creation/update time

This is useful for a number of things. For example, listing users that need to
rotate their passwords after some event. It also provides a safer way for code
to determine that a user password has changed without needing to set a handler
for the password change event (which is a more fragile approach).
