move console sample's interactive tests to two different CppUnit testsuites: InteractiveInputTestCase which requires user input and InteractiveOutputTestCase which outputs stuff to be checked from the user.

Leave in the console sample only a barebone console application (i.e. a real example).

Closes #11960
