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 skip option

Changes since RFC v2:
- Change fake suite and test case names.
- Add a few ASSERT statements.
Changes since RFC v1:
- This is a new patch
