Dr. Stefan Schimanski a2fa41b73f Implement resource accounting for pods with the Mesos scheduler
This patch

- set limits (0.25 cpu, 64 MB) on containers which are not limited in pod spec
  (these are also passed to the kubelet such that it uses them for the docker
  run limits)
- sums up the container resource limits for cpu and memory inside a pod,
- compares the sums to the offered resources
- puts the sums into the Mesos TaskInfo such that Mesos does the accounting
  for the pod.
- parses the static pod spec and adds up the resources
- sets the executor resources to 0.25 cpu, 64 MB plus the static pod resources
- sets the cgroups in the kubelet for system containers, resource containers
  and docker to the one of the executor that Mesos assigned
- adds scheduler parameters --default-container-cpu-limit and
  --default-container-mem-limit.

The containers themselves are resource limited the Docker resource limit which
the kubelet applies when launching them.

Fixes mesosphere/kubernetes-mesos#68 and mesosphere/kubernetes-mesos#304

Joerg Schad 7af8bf6ed3 Add static pod support to mesos scheduler and executor.
- the mesos scheduler gets a --static-pods-config parameter with a directory with
  pods specs. They are zipped and sent over to newly started mesos executors.
- the mesos executor receives the zipper static pod config via ExecutorInfo.Data
  and starts up the pods via the kubelet FileSource mechanism.
- both - the scheduler and the executor side - are fully unit tested
