Use the same name in volumeMounts and volumes
In some example files of vSphere volumes, volumeMounts and volumes
have different names. kubectl create will fail with error message
saying the pod is invalid because volumeMount with the name is not
found.

fixing Cassandra shutdown example to avoid data corruption
Hi,
I was playing with Cassandra example stored in the Kubernetes project and I encountered issues on shutdown (not anytime). After checking it looks like the shutdown of a node is brutal and data corruption may occur during a flush on disk. To avoid that, I'm suggesting a hook to gracefully shutdown Cassandra before stopping the container.
Here are logs of corruption after a pod delete:

Curating Owners: examples/mysql-wordpress-pd
cc @jeffmendoza
In an effort to expand the existing pool of reviewers and establish a
two-tiered review process (first someone lgtms and then someone
experienced in the project approves), we are adding new reviewers to
existing owners files.
If You Care About the Process:
------------------------------
We did this by algorithmically figuring out who’s contributed code to
the project and in what directories. Unfortunately, that doesn’t work
well: people that have made mechanical code changes (e.g change the
copyright header across all directories) end up as reviewers in lots of
places.
Instead of using pure commit data, we generated an excessively large
list of reviewers and pruned based on all time commit data, recent
commit data and review data (number of PRs commented on).
At this point we have a decent list of reviewers, but it needs one last
pass for fine tuning.
Also, see https://github.com/kubernetes/contrib/issues/1389.
TLDR:
-----
As an owner of a sig/directory and a leader of the project, here’s what
we need from you:
1. Use PR https://github.com/kubernetes/kubernetes/pull/35715 as an example.
2. The pull-request is made editable, please edit the `OWNERS` file to
remove the names of people that shouldn't be reviewing code in the
future in the **reviewers** section. You probably do NOT need to modify
the **approvers** section. Names asre sorted by relevance, using some
secret statistics.
3. Notify me if you want some OWNERS file to be removed. Being an
approver or reviewer of a parent directory makes you a reviewer/approver
of the subdirectories too, so not all OWNERS files may be necessary.
4. Please use ALIAS if you want to use the same list of people over and
over again (don't hesitate to ask me for help, or use the pull-request
above as an example)

PodFitsPorts has been replaced by PodFitsHostPorts
**What this PR does / why we need it**:
in [defaults.go](https://github.com/kubernetes/kubernetes/blob/master/plugin/pkg/scheduler/algorithmprovider/defaults/defaults.go)
> PodFitsPorts has been replaced by PodFitsHostPorts for better user understanding.
For backwards compatibility with 1.0, PodFitsPorts is registered as well.
So , I replaced PodFitsPorts with PodFitsHostPorts in scheduler examples
