One of the HanaSR test is about crashing one cluster node running HANA. Crash command is executed through a ssh channel. Problem is that, as soon as the system crash, the ssh connection is interrupted leaving the ssh client blocked. The idea is: compose the remotely executed command with a sleep and then the crash, run these two in background. It gives time to the ssh client to close the session before the crash happening. Remove the timepout=0 behavior, stop forwarding to run_ssh_command all the args content.

http://openqaworker15.qa.suse.cz/tests/297287 🟢 This VR is before to align to Move Public Cloud ssh opts to CLI in HanaSR tests #20169. It demonstrates that delaying the crash command remotely to allow ssh to return before the crash is triggered, helps about not hanging the terminal : http://openqaworker15.qa.suse.cz/tests/297286#step/Crash_site_a-primary/420
Test fails later on in the same test module : wait_ssh_disapear is completed http://openqaworker15.qa.suse.cz/tests/297286#step/Crash_site_a-primary/423 . Here the remote system reply to
is_system_runningwithrunninghttp://openqaworker15.qa.suse.cz/tests/297286#step/Crash_site_a-primary/439 and here is the same again http://openqaworker15.qa.suse.cz/tests/297286#step/Crash_site_a-primary/452 . But here the same command timeout http://openqaworker15.qa.suse.cz/tests/297286#step/Crash_site_a-primary/466http://openqaworker15.qa.suse.cz/tests/297308
