David Porter 1c75c2cda8 test: Add e2e to verify static pod termination ...

Add a node e2e to verify that if a static pod is terminated while the
container runtime or CRI returns an error, the pod is eventually
terminated successfully.

This test serves as a regression test for k8s.io/issue/113145 which
fixes an issue where force deleted pods may not be terminated if the
container runtime fails during a `syncTerminatingPod`.

To test this behavior, start a static pod, stop the container runtime,
and later start the container runtime. The static pod is expected to
eventually terminate successfully.

To start and stop the container runtime, we need to find the container
runtime systemd unit name. Introduce a util function
`findContainerRuntimeServiceName` which finds the unit name by getting
the pid of the container runtime from the existing
`ContainerRuntimeProcessName` flag passed into node e2e and using
systemd dbus `GetUnitNameByPID` function to convert the pid of the
container runtime to a unit name. Using the unit name, introduce helper
functions to start and stop the container runtime.
