DefaultOOMHandler should mark preempted containers as killed

      Description

      DefaultOOMHandler today kills a selected container by sending kill -9 signal to all processes running within the container cgroup.

      The container would exit with a non-zero code, and hence treated as a failure by ContainerLaunch threads.

      We should instead mark the containers as killed.
