MINOR: tasks/activity: report the context switch and task wakeup rates
It's particularly useful to spot runaway tasks to see this. The context
switch rate covers all tasklet calls (tasks and I/O handlers) while the
task wakeups only covers tasks picked from the run queue to be executed.
High values there will indicate either an intense traffic or a bug that
mades a task go wild.
