Nick Hill b373b5102a [Tests] Shutdown test RemoteVLLMServer cleanly (#36950) ...

Recent PR #33949 changed the teardown logic of the RemoteVLLMServer test utility class to
send SIGTERM to all vllm (sub)processes at once, which breaks the clean/coordinated
shutdown logic that assumes only the top-level process will receive a signal (for example
when running in a container that's shut down).

This caused a bunch of errors and stacktraces in some test logs, even though those tests
still pass. We should still attempt a normal shutdown and only kill other procs if they are
still running after a few seconds.

Example: tests/v1/distributed/test_external_lb_dp.py::test_external_lb_completion_streaming
