Continuous Integration (CI)

Instead of using the the testmask.txt file to store the tests mask, we can use some variable in the ci_tests.cfg file.
The name of the variable will be:
RUN_TEST_<exp>
CHECK_PRODUCTS_<exp>
CHECK_PRODUCT_SIZE_<exp>

The value to assign to these variable is:
0 = disable
1 = enable

These variable will be set to a default value in the [default] section of the ci_tests.cfg
then, if needed, in the CI test section the default value can be changed.

These variables will be combined to be the argument of the option --testmask of the CI regression script.
