Enhance the repo to have a 'build all' option

Would be super useful to have a script that would kick off each test in turn defined in the semaphore build config.

The script should stop at the first failure.

Ideally, the script could be passed a keyword, e.g. `ksql`, that can be used to filter the list of tests.

That can then be used by the likes of me to test new releases of KSQL, rather than currently having to run it manually.

Or...

Have ability to kick off a build with a specific tag of CP and Ksql versions, e.g. run with CP 5.5.0 and ksqlDB tag 0.9.0-rc245 and then have the build server run all the tests.

(This of course assumes the tests are stable).
