This uses the remote side "timeout" command to implement a timeout for the actual command the user intends to run. The arguments given are the simplest possible to be made compatible with "timeout" implementations such as the ones given by busybox.
While it's not possible to have a functional test at this point (because the test would need a second and properly configured machine), the example API script should serve as a proof that this implementation behaves correctly:
$ python3 examples/apis/utils/ssh_timeout.py

This is a follow up to #5654
