Having access to historical performance counters will be useful when we encounter performance issues. This PR creates a program to install sysstat on VmHosts to enable that. After this, sysstat will collect a performance counter samples every minute, which can be analyzed using the sar command: ``` $ sar -f /var/log/sysstat/sa[date] [options] ```
