Fix 7 broken example e2e tests
Fixes#27325, Fixes#27727
7 broken example e2e tests:
- [x] Spark
* `namespace` is specified in example yaml files which conflict with e2e test namespaces, fixed by removing the namespace in yaml (the yaml files of [spark example](https://github.com/kubernetes/kubernetes/tree/master/examples/spark) doesn't need the namespace specified since it's specified in its context) -- cc @k82 who added namespace to Spark example in #23807
* wait for pods to exist before determining if it's running
- [x] Hazelcast
* wait for pods to exist before determining if it's running
- [x] Redis
* image `kubernetes/redis:v2` is not found, changed to `kubernetes/redis:v1` instead
* wait for pods to exist before determining if it's running
- [x] Celery-RabbitMQ
* remove 1 redundant call to `forEachPod`
* wait for pods to exist before determining if it's running
- [x] Cassandra
* fix `kubectl exec` on incorrect pod name
* fix getting endpoint ip addresses before creating pods
* wait for pods to exist before determining if it's running
- [x] Storm
* wait for pods to exist before determining if it's running
- [x] RethinkDB
* wait for pods to exist before determining if it's running

Reapply ScheduledJob tests (2ab885a53a)
Re-applied the ScheduledJob tests (#25737) which were reverted due to an integration test error in #27184.
The problem was in `TestBatchGroupBackwardCompatibility` which is testing backwards compatibility for storing jobs (`extensions/v1beta1` vs `batch/v1`), which is not needed for `batch/v2alpha1`. I've added a skip to aforementioned test for that group. See `test/integration/master_test.go` for the actual fix.

GCE provider: Limit Filter calls to regexps rather than insane blobs
Filters can't exceed 4k, and GET requests against the GCE API are also limited, so these break down in different ways at different cluster counts. Fix it by introducing an advisory `node-instance-prefix` configuration in the GCE provider that can hint the `EnsureLoadBalancer`/`UpdateLoadBalancer code` (and the firewall creation/update code). If it's not there, or wrong (a hostname that's registered violates it), just ignore it and grab the whole project.
Fixes#27731

Add integration test for binding PVs using label selectors
Adds an integration test for persistent volume claim label selector.
Many integration tests delete all keys in etcd as part of their cleanup.
To run these tests in parallel we must run several etcd daemons, each on
different port and pass etcd url to the test suite.

This PR:
1) Cleans up the `ConformanceContainer` a bit
2) Add termination message test
This test proves #23639, without #23658, the test could not pass.

Filter seccomp profile path from malicious .. and /
Without this patch with `localhost/<some-releative-path>` as seccomp profile one can load any file on the host, e.g. `localhost/../../../../dev/mem` which is not healthy for the kubelet.
