Bug 1112: Updated toaster-it configuration to use InMemory Data Store.

As it turned out toaster-it used configuration with legacy data store
and not new one.

Updated controller config for toaster-it to have latest configuration
for MD-SAL.

controller.xml was restructured in such way, it is
easy to compare 01-mdsal.xml with controller.xml using diff
or meld tool.
