8c776b7eb9 host port mapping should be more consistent between scheduler and
controller-manager in k8sm:
  - rename host_port_endpoints flag to host-port-endpoints
  - host port mapping strategy in scheduler should be driven by host-port-endpoints flag
  - added host-port-endpoints to known flags
  - docs: scheduler should also be configured with host-port-endpoints
  - task recovery: be explicit about excluding mirror pods

- code cleanup
- removed hacky podtask.And func; support minimal resources for static pods when resource accounting is disabled
- removed zip archive of static pods, changed to gzip of PodList json
- pod utilities moved to package podutil
- added e2e test
- merge watched mirror pods into the mesos pod config stream

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

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

932c58a497 Kubernetes Mesos integration
This commit includes the fundamental components of the Kubernetes Mesos
integration:

* Kubernetes-Mesos scheduler
* Kubernetes-Mesos executor
* Supporting libs

Dependencies and upstream changes are included in a separate commit for easy
review.

After this initial upstream, there'll be two PRs following.

* km (hypercube) and k8sm-controller-manager #9265
* Static pods support #9077
