  1. Add Intel RDT support 

    Add --rdt-class=COS to the create and run command to enable the
assignment of a container to a Class of Service (COS). The COS
represents a part of the cache based on the Cache Allocation Technology
(CAT) feature that is part of Intel's Resource Director Technology
(Intel RDT) feature set. By assigning a container to a COS, all PID's of
the container have only access to the cache space defined for this COS.
The COS has to be pre-configured based on the resctrl kernel driver.
cat_l2 and cat_l3 flags in /proc/cpuinfo represent CAT support for cache
level 2 and 3 respectively.
