Moved scheduler from containers back to being a global.
...
It makes more sense to have a scheduler (or runqueue pair) per-cpu
rather than per-container. This provides more flexible global scheduling
policy that is also simpler due to all scheduling details being controlled
from a single point.

CML2 rule file is autogenerated from arm.cml and the containers template
...
Container rules are too many and repetitive for each container. With this
change, the cml file is autogenerated from a container template cml and
the architecture cml, e.g. arm.cml. -c option determines the number of
containers. See build.py -h for more.
