Add improvements to colorizing script

Add improvements to colorizing script

[Issue#]        N/A
[Feature]       Adds following features to script colorizing test output:
                    * sc_tests_all now passes arguments to launched binaries.
                    * sc_test_launch now allows for absolute path to test binary.
                    * If any test case fails, script provides a command to launch any test case
                      explicitly.
                    * Minor corrections in test result display.
[Cause]         N/A
[Solution]      N/A
[Verification]  Build, install, run:
                    * sc_tests_all - all tests should show up,
                    * sc_tests_all -t ContainerSuite - only ContainerSuite test suite should show,
                    * sc_test_launch /bin/security-containers-server-unit-tests - should launch
                      security-containers-server-unit-tests.
