e2e: add TERM trap to pod sleep command

Browse Source 
This should avoid the 30s delay caused by shell not responding to SIGTERM, and can only be killed by SIGKILL.

If the pod is deleted with the namespace during cleanup, this also makes cleanup faster, and frees up the resources for the next test cases faster.
