MINOR: activity: add configuration and CLI support for "profiling.tasks"
This is a new global setting which enables or disables CPU profiling
per task. For now it only sets/resets the variable based on the global
option "profiling.tasks" and supports showing it as well as setting it
from the CLI using "show profiling" and "set profiling". The option will
be used by a future commit. It was done in a way which should ease future
addition of profiling options.
