Add four tests to executor_test.c to test behavior of filtering attributes.
- parse_filter_attr_test - to test the parsing of inputted filters
- filter_attr_test - to test the filtering procedure on attributes
- filter_attr_empty_test - to test the behavior when all tests are filtered out
- filter_attr_skip_test - to test the configurable filter_action=skip option
