Fixed namespace name to spark-cluster
Just changed the namespace from **default** to **spark-cluster** in the spark example docs.
The guestbook-go example is broken because the latest tag of redis has
moved to redis 3.0 which speaks a new protocol. This means that the
slaves, which have fixed 2.0 versions, will error out on the protocol:
```
[7] 15 May 23:37:44.403 # Can't handle RDB format version 7
[7] 15 May 23:37:44.403 # Failed trying to load the MASTER synchronization DB from disk
[7] 15 May 23:37:45.333 * Connecting to MASTER redis-master:6379
[7] 15 May 23:37:45.427 * MASTER <-> SLAVE sync started
```
In this case the app simply never persists data.

The codec factory should support two distinct interfaces - negotiating
for a serializer with a client, vs reading or writing data to a storage
form (etcd, disk, etc). Make the EncodeForVersion and DecodeToVersion
methods only take Encoder and Decoder, and slight refactoring elsewhere.
In the storage factory, use a content type to control what serializer to
pick, and use the universal deserializer. This ensures that storage can
read JSON (which might be from older objects) while only writing
protobuf. Add exceptions for those resources that may not be able to
write to protobuf (specifically third party resources, but potentially
others in the future).

Deleting duplicate code from federated-apiserver.Run()
This removes most of duplicate code from federated-apiserver.Run().
The code remaining is related to storage or authz and authn.
https://github.com/kubernetes/kubernetes/pull/24787 refactors the storage related code.
I am still figuring out authz and authn.

Refactored SeedProvider and Updated Docker
This is a redo of the last PR that I munged 😄
- fixed maven build folder structure
- updated build to C* 3.4
- refactored Seed Provider - improved error handling, updated default SeedProvider code
- added start of unit tests. Not as comprehensive as I would like
- updated docker image to debian:jessie
- installed openjdk 8
- added some docker fu to make the image smaller
- updated docker to C* 3.4 and update yaml
- updated README content. Added a section about the docker, and the SeedProvider
Have not had a chance to test the docker on k8s, because I do not have a local docker repo.
NOTE: someone needs to push the docker image into the google repo. Not sure what the process is ... I will submit another PR request with changes to the yaml files.

Move internal types of job from pkg/apis/extensions to pkg/apis/batch
This addressed the job part of #23216, this is still WIP. Will notify once finished. I'd like to have it in before starting working on ScheduledJob.

Intial draft on SeedProvider docs
Alsa more documentation. We need to reference the config section in the example docs. There are multiple PRs open in those docs, so at this point I do not want to make a mess.
Let me know if there are docs standard template that will make this more pretty.

update gb-frontend image. New image includes the change in PR # 23381.
Update to use the gcr.io/google-samples/gb-frontend:v4 image. New image includes the change in https://github.com/kubernetes/kubernetes/pull/23381.
Add tests to watch behavior in both protocols (http and websocket)
against all 3 media types. Adopt the
`application/vnd.kubernetes.protobuf;stream=watch` media type for the
content that comes back from a watch call so that it can be
distinguished from a Status result.

Add mpio support for iscsi
This allows the iscsi volume to check if a iscsi device belongs to a mpio device
If it does belong to the device then we make sure we mount the mpio device instead of
the raw device.
The code is based on the current FibreChannel volume support for mpio
example
/dev/disk/by-path/iqn-example.com.2999 -> /dev/sde
Then we check
/sys/block/[dm-X]/slaves/xx
until we find the [dm-X] containing /dev/sde and mount it
Additional work that can be done in future
1. Add multiple portal support to iscsi
2. Move the FibreChannel volume provider to use the code that has been extracted
If it does belong to the device then we make sure we mount the mpio device instead of
the raw device.
Heuristics
Login into /dev/disk/by-path/iqn-example.com.2999 -> /dev/sde
Check if sde existsin in /sys/block/[dm-X]/slaves/xx
If it does mount /dev/[dm-x] which will look like /dev/mapper/mpiodevicename in mount
examples/iscsi has more details

Flexvolume: Add support for multiple secrets
This PR adds support to pass multiple secrets for flexvolume plugins.
To allow multiple secrets, secrets are now passed as:
"kubernetes.io/secret/id-rsa":"value-2\r\n\r\n","kubernetes.io/secret/id-rsa.pub":"value-1\r\n"

phase 2 of cassandra example overhaul
Here's the next iteration in overhauling this example, towards https://github.com/kubernetes/kubernetes/issues/20961. This removes the pod adoption part, but doesn't (yet) otherwise change any of the resources used.
It also includes some README cleanup, and removes some explicit specification of labels in the rc yaml.
This PR doesn't yet add any commentary on how we're using the seed provider (re: https://github.com/kubernetes/kubernetes/issues/20961#issuecomment-190405959 etc.). Maybe we should add that.
Also: LMK if this PR should include any changes to the links out to the docs.

Implement a streaming serializer for watch
Changeover watch to use streaming serialization. Properly version the
watch objects. Implement simple framing for JSON and Protobuf (but not
YAML).

examples/guestbook/php-redis: don't reopen stdio fds
/etc/apache2/apache2.conf was configured to log in this way:
> ErrorLog /proc/self/fd/2
> CustomLog /proc/self/fd/1 combined
This causes apache to reopen the already-opened fds. It works fine when
the file descriptors are pipes or ttys but it fails when they are Unix
sockets because sockets cannot be opened with the open() syscall. The
issue happens when apache is connected to systemd-journald, like in the
rkt container run-time.
This patch uses "cat" to directly write to the stdio fds without
reopening them. apache2.conf now looks like:
> ErrorLog "|$/bin/cat 1>&2"
> CustomLog "|/bin/cat" combined
It works both with Docker and rkt (tested with and without
--interactive).
Symptoms:
> [ 2673.478868] apache2-foreground[4]: (6)No such device or address:
> AH00091: apache2: could not open error log file /proc/self/fd/2.
