New release for pause container
**What this PR does / why we need it**:
This PR bumps the TAG for the pause container so that we can build a new release with affecting older Kubernetes releases. Once the new release has been pushed to gcr.io/google_containers, I will follow up with a PR to update the kubelet/runtimes to use the new container.
In addition to bumping the tag, this PR also:
* Updates the pause Makefile to reflect a name change in the arm compiler used in kube-cross
* Adds a very simple version string to pause.c to help troubleshoot issues like #50865 in the future.

Implementing predicates ordering
**What this PR does / why we need it**: implements predicates ordering for the scheduler
**Which issue(s) this PR fixes** : Fixes#53812
**Special notes for your reviewer**:
@bsalamat @gmarek @resouer as discussed on slack, to implement ordering we have to choices:
- use a layered approach with a list that indexes the order of the predicates map
- change the underlying data structure used to represent a collection of predicates (a map in our case) into a list of predicates objects.
Going with this solution might be "cleaner" but it will require a lot of changes and will increase the cost for accessing predicates from O(1) to O(n) (n being the number of predicates used by the scheduler).
we might go with this solution for now. If the number of predicates start growing, we might switch to the second option.
**Release note**:
```release-note
adding predicates ordering for the kubernetes scheduler.
```

Reduce CPU and memory requests for Metrics Server Nanny

Collect all the assorted image URLs from e2e tests in one place
utils/image/manifest has an additional `arch` parameter, which determines
whether an image ends in `-$ARCH` (like `-amd64`).
All locations that previously had gcr.io urls referenced in costants or inline
have been updated to refere test/utils/image.
**What this PR does / why we need it**:
Previously, all sorts of `gcr.io/` URLs were scattered all over the E2E tests codebase. This PR unifies them all in one place, making it easier to see what is needed to run the E2E tests, as well as making sure all tests use the same version of docker images.
Heptio is working on a project to get the E2E tests running in airgapped environments. Part of that task is collecting all images in one place. A future PR will allow modification of the registry URLs to point at a private docker registry.
**Special notes for your reviewer**:
Two images, https://github.com/kubernetes/kubernetes/pull/56716/files#diff-e3afa632328a4a5271f4b8578faa34bdL318 and https://github.com/kubernetes/kubernetes/pull/56716/files#diff-7dc1ebd3b2f2f6ca1ff248e6601016a6L104 are now pointing to slightly different images. If this breaks the E2E tests, the variables can be duplicated to restore the old dependencies, and the duplicates can be removed at a later date.

Version bump to etcd v3.2.11, grpc v1.7.5
Fix https://github.com/kubernetes/kubernetes/issues/56114: Update to etcd client 3.2.11
Version bumps:
- etcd from 3.1.10 to 3.2.11
- grpc from 1.3.0 to 1.7.5
- grpc-gateway from v1.1.0-25-g84398b9 to v1.3.0
TODO:
- [x] Apply etcd [3.2 client upgrade guide](https://github.com/coreos/etcd/blob/master/Documentation/upgrades/upgrade_3_2.md)
- [x] Apply grpc API changes in 1.6.0 and 1.7.0 [release notes](https://github.com/grpc/grpc-go/releases)
- [x] bbolt was pulled in transitively, why? We have tests that embed etcd, so we must vendor the etcd server and all it's dependencies.
- [x] Upgrade to containerd v1.0.0? Currently kubernetes depends on containerd v1.0.0-beta.2-159-g27d450a0 which depends on grpc v1.3.0, but containerd v1.0.0 depends on grpc 1.7.2. Not needed. The containerd grpc upgrade required [no code changes](ce3e32680d).
- [x] Fix all failing tests
- [x] Ensure we can safely upgrade grpc to 1.7.5 given that docker and cAdvisor still depend on grpc 1.3.0 (both in the versions we vend and on master for both projects). Should we hold off on this change until we have a docker release that uses gprc 1.7.x?
- [x] Wait for grpc 1.7.5 to be released (it will include https://github.com/grpc/grpc-go/pull/1747). Once released, bump grpc version in this PR and remove workarounds in `hack/godep-save.sh`.
Transitive dependencies on grpc:
- docker depends on grpc, but according to the package dependency graph (`go list -f '{{ .Deps }}'`) there are no dependencies from kubernetes to grpc via docker packages.
- containerd v1.0.0 depends on grpc 1.7.2, we should upgrade to containerd v1.0.0 soon, this can be done in a separate PR
- cadvisor depends on grpc 1.3.0 on master, it should upgrade it to grpc 1.7.5, this can be done in a separate PR
**Release note**:
```release-note
Upgrade to etcd client 3.2.11 and grpc 1.7.5 to improve HA etcd cluster stability.
```
