move  from daemon_restart.go to framework/util.go

**What this PR does / why we need it**:
Moves the func `nodeExec` from daemon_restart.go to framework/util.go. This is the correct file for this func and is a more intuitive pkg for other callers to use. This is a small step of the larger effort of restructuring e2e tests to be more logically structured and easier for newcomers to understand.
