[Federation][e2e] Use correct default dns name in e2e-testing
After some kubefed changes, the environment variable did not get propagated and we defaulted back to 'federation' instead of 'e2e-federation'. This fixes ongoing service test issues in e2e.

Create EnsureExists class addons before Reconcile class addons
From #42757.
The addon-manager creates "Reconcile" class addons before creates "EnsureExists" class addons, which is not the best order. The "EnsureExists" class addons tend to be some default configurations like `default-storage-class` and `default kube-dns ConfigMap` (being added in #42757), and we would like to have these default configurations created before other addons are created.

dockershim: Fix the race condition in ListPodSandbox
In ListPodSandbox(), we
1. List all sandbox docker containers
2. List all sandbox checkpoints. If the checkpoint does not have a
corresponding container in (1), we return partial result based on
the checkpoint.
The problem is that new PodSandboxes can be created between step (1) and
(2). In those cases, we will see the checkpoints, but not the sandbox
containers. This leads to strange behavior because the partial result
from the checkpoint does not include some critical information. For
example, the creation timestamp'd be zero, and that would cause kubelet's
garbage collector to immediately remove the sandbox.
This change fixes that by getting the list of checkpoints before listing
all the containers (since in RunPodSandbox we create them in the reverse
order).

[Federation] Generate a random nodePort for each service object in e2e tests.
We now run e2e tests in parallel in the CI environment and nodeports are a single available range of numbers for all the service objects, so they have to be unique for each service object.

Adds default kube-dns configmap
From #42746.
Using 1.4 kubelet with 1.6 master is causing upgrade test failures. Because kubelet doesn't understand optional configmaps and there is no kube-dns configmap exist, kubelet will crash.
This PR adds an empty kube-dns configmap as an "EnsureExists" class addon for fixing that.
Note: The addon-manager creates "Reconcile" class addons before creates "EnsureExists" class addons, which is not the order we want. I will soon have another PR to reverse this order.

Only create the symlink when container log path exists
When using `syslog` logging driver instead of `json-file`, there will not be container log files such as `<containerID-json.log>`. We should not create symlink in this case.

This change allows validators to pass warnings as well as errors. This
was needed because of how support for docker 1.13+ and the new EE and CE
versions is currently being handled.
We now run e2e tests in parallel in the CI environment and nodeports are
a single available range of numbers for all the service objects, so they
have to be unique for each service object.

e2e: fix restarting the apiserver

Add taint-based evictions to feature-gates
This is not a PR, it's a repro, so please treat is as an issue:)
I was trying to move from dedicated flag to feature flag for Taint eviction feature and failed, as I'm unable to pass feature flag in the commandline. PR I tried is "included", and the results are following:
```
I0307 14:55:14.288374 5 feature_gate.go:174] feature gates: map[TaintBasedEvictions:true AffinityInAnnotations:true]
I0307 14:55:14.288479 5 feature_gate.go:174] feature gates: map[ExperimentalCriticalPodAnnotation:true]
...
I0307 14:55:37.358358 5 controllermanager.go:445] TaintBasedEvictions feature enabled: false
I0307 14:55:37.358368 5 controllermanager.go:446] AffinityInAnnotations feature enabled: false
```
As it can be seen unlike all other "feature gate" tests, I didn't write dedicated unit test that manipulates gates by hand, but added `--feature-gates` flag to the controller-manager command line.
I added 'AffinityInAnnotations' as a sanity check and it failed as well. So it seems to me that something is not working.

Most of recent federation service tests are failing with timeouts. although some times they do pass, giving kind of flaky nature. So increasing the timeout waiting for service shard to appear in federated cluster from 1 min to 5 mins.

[Federation] Use and return created replicaset instead of the passed object.
Passed replicaset object doesn't contain object name, but has a prefix set in `GenerateName`. However, we need to operate on the object name later to uniquely identified the created object. So we need the created object with the name set by the API server.
