Subject: [PATCH 1/2] Set minimum size of a container

This prevents people from explicity setting memory or cpu request to 0 for their
containers. While such pods will be the first to be kicked out when the
cluster is low on resources, they will continue to run for free at other times.

With this in place the scheduler will reject the container from running with
an appropriate message to the user.

Subject: [PATCH 2/2] Update the default limit and request for containers

This sets it such that the CPU to Memory ratio aligns with our CPU SU definition
of 1 CPU to 4 Gi of Memory.

Note that I lowered the CPU limits and request instead of only increasing the
memory.
