Log Message:
-----------
[Build] Update STF environment to JDK 11

* Updates STF test runner to use JDK 11 docker container
* Remove unsupported -t parameter from timeout command
* JDK 9 introduced java modules. Now eclipse is asking to create a file
for this and STF Bot is extended to uncheck the creation of this file.
Otherwise the create dialog would never finish.
