Test for Sporadic Server (ss):

this is a part of the classic Hartik demo Aster.

it is based on test 17 (h), and the JobControl Task uses an
SOFT_TASK_MODEL served by a sporadic server
There are two "dummy" tasks that increment a counter and print
the value. One uses a SOFT_TASK_MODEL served by sporadic server,
the other uses a NRT_TASK_MODEL handled by RR module.
