[Feature]: Allow test case selection

[ReinhardKeil]

Suggest to extended SDSIO-Server with features for test case selection.

Monitor interface

https://arm-software.github.io/SDS-Framework/main/theory.html#sdsio-server-monitor-interface

Extend SDSIO_MON_FLAGS with TestCase. This selects a specific test case from the sdsio.yml and is intended for interactive usage.

| WORD | WORD     | WORD       | WORD |

Command Line

Extend the option --playback with a number

--playback 2    // use test case 2 from sdsio.yml file
--playback *    // playback all test cases
