Disable mount propagation for windows containers

**What this PR does / why we need it**:

Windows containers don't support mount propagation. This PR disables it for windows containers.

Without this PR, windows containers creation would fail with error:

 Error: Error response from daemon: invalid bind mount spec "c:\\var\\lib\\kubelet\\pods\\a260a7c4-1852-11e8-bb1d-000d3a19c1da\\volumes\\kubernetes.io~secret\\default-token-rj7qv:c:/var/run/secrets/kubernetes.io/serviceaccount:ro,rslave": invalid volume specification: 'c:\var\lib\kubelet\pods\a260a7c4-1852-11e8-bb1d-000d3a19c1da\volumes\kubernetes.io~secret\default-token-rj7qv:c:\var\run\secrets\kubernetes.io\serviceaccount:ro,rslave'

Fixes for HTTP/2 max streams per connection setting

**What this PR does / why we need it**:
This PR makes two changes.  One is to introduce a parameter
for the HTTP/2 setting that an api-server sends to its clients
telling them how many streams they may have concurrently open in
an HTTP/2 connection.  If left at its default value of zero,
this means to use the default in golang's HTTP/2 code (which
is currently 250; see https://github.com/golang/net/blob/master/http2/server.go).

The other change is to make the recommended options for an aggregated
api-server set this limit to 1000.  The limit of 250 is annoyingly low
for the use case of many controllers watching objects of Kinds served
by an aggregated api-server reached through the main api-server (in
its mode as a proxy for the aggregated api-server, in which it uses a
single HTTP/2 connection for all calls proxied to that aggregated
api-server).

**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
Fixes #60042

**Special notes for your reviewer**:

**Release note**:

```release-note
Introduced `--http2-max-streams-per-connection` command line flag on api-servers and set default to 1000 for aggregated API servers.

- An automatic assignment of critical priorities to pods based on critical pod annotation for backwards compatibility including some unit tests.

deprecate --show-all

`--show-all` is a pod-only filter that only affects human-readable printing of pods and only from `kubectl get`.  It hides pods which are in a terminal state.  Even at the beginning this was questionable, since you often (usually?) want to see the pods that have failed: all happy pods are alike, but every unhappy pod is unhappy in its own way.  In addition, it only worked on human-readable printers.  Doing a `-o name` or `-o yaml` showed a different set of results!

Per the mailing list discussion here: https://groups.google.com/forum/#!topic/kubernetes-sig-cli/0SxgDxObxD0

```release-note
`--show-all` (which only affected pods and only for human readable/non-API printers) is now defaulted to true and deprecated.  It will be inert in 1.11 and removed in a future release.
```

Don't create no-op iptables rules for services with no endpoints

Currently for all services we create `-t nat -A KUBE-SERVICES` rules that match the destination IPs (ClusterIP, ExternalIP, NodePort IPs, etc) and then jump to the appropriate `KUBE-SVC-XXXXXX` chain. But if the service has no endpoints then the `KUBE-SVC-XXXXXX` chain will be empty and so nothing happens except that we wasted time (a) forcing iptables-restore to parse the match rules, and (b) forcing the kernel to test matches that aren't going to have any effect.

This PR gets rid of the match rules in this case. Which is to say, it changes things so that every incoming service packet is matched *either* by nat rules to rewrite it *or* by filter rules to ICMP reject it, but not both. (Actually, that's not quite true: there are no filter rules to reject Ingress-addressed packets, and I *think* that's a bug?)

I also got rid of some comments that seemed redundant.

The patch is mostly reindentation, so best viewed with `diff -w`.

Partial fix for #56842 / Related to #56164 (which it conflicts with but I'll fix that after one or the other merges).

**Release note**:
```release-note
Removed some redundant rules created by the iptables proxier, to improve performance on systems with very many services.

Update get.go to use server-side printing

Addresses part of https://github.com/kubernetes/kubernetes/issues/58536
Adds support for server-side changes implemented in https://github.com/kubernetes/kubernetes/pull/40848 and updated in https://github.com/kubernetes/kubernetes/pull/59059

@deads2k per our discussion, opening this as a separate PR.
This wires through a per-request use of `as=Table;...` header parameters 
using the resource builder from the `kube get` command.



#### Items to consider going forward:

- [ ] Figure out how to handle sorting when dealing with multiple Table objects from the server
- [ ] Figure out sorting when dealing with a mixed response from the server consisting of Tables and normal resources (`--sort-by` is handled in this PR by falling back to old behavior)
-  [ ] Filtering: How should we filter Table objects? Separate filter for rows? Filter on jsonpath? We have access to partial object metadata for each table row - not enough to know how to filter pods, for example but we could request that the original object be included along with each Table.Row by adding an `includeObject` param in the client request.

#### Resources that do not yet support Table output

- [ ] Namespaces
- [ ] Services
- [ ] Service catalog resources: https://github.com/kubernetes-incubator/service-catalog/blob/master/pkg/apis/servicecatalog/v1beta1/types.go

**Release note**:
```release-note
NONE
```

We can group custom resources into categories i.e.
use them with kubectl get all.

PSP plugin: allow authorizing via "use" verb in policy API group

In order to determine whether a service account/user has access to PSP, PodSecurityPolicy admission plugin tests whether a service account/user is authorized for "use" verb in `extensions` API group.
