This by default would be scheduling to all cells since all cells
would be enabled at the time of creation unless specified otherwise.
Since the list of enabled cells are stored as a global cache on the
host_manager, a reset() handler for the SIGHUP signal has also been
added in the scheduler. Hence upon every create-cell/enable-cell/
disable-cell operation the scheduler has to be signaled so that the
cache is refreshed.
