Added new measurement module, sysstat

This module runs in parallel with cyclictest and will every minute
use sysstat/sadc to collect all available system statistics.  These
statistics is both added as a single file to the tarball and embedded
into the summary.xml.

Also changed the polling time which checks if measurement and load modules
are alive from every second to every minute.
