These appear to be optional, although the documentation doesn't explicitly say
that. If they are optional, I would update the docs to say so, and then, here,
just do "network_handler::StringResultCallback()", which creates a null
callback.

[stevenjb, 2015/01/13 23:45:39]

Correct. We should update the 'Note on callbacks' comment in
network_configuration_handler.h. I will add that some time soon if you don't
want to do that here.

Working on updating the NetworkConfigurationHandler documentation in
https://codereview.chromium.org/799313004/.

[mukesh agrawal, 2015/01/15 03:01:48]

Done.
