ApplyTo adds the admission chain to the server configuration the method lazily initializes a generic plugin
that is appended to the list of pluginInitializers.
apiserver.Config will hold an instance of SharedInformerFactory to ensure we only have once instance.
The field will be initialized in apisever.SecureServingOptions

Delete "hard-coded" default value in flags usage.
**What this PR does / why we need it**:
Some flags of kubernetes components have "hard-coded" default values in their usage info. In fact, [pflag pkg](https://github.com/kubernetes/kubernetes/blob/master/vendor/github.com/spf13/pflag/flag.go#L602-L608) has already added a string `(default value)` automatically in the usage info if the flag is initialized. Then we don't need to hard-code the default value in usage info. After this PR, if we want to update the default value of a flag, we only need to update the flag where it is initialized. `pflag` will update the usage info for us. This will avoid inconsistency.
For example:
Before
```
kubelet -h
...
--node-status-update-frequency duration Specifies how often kubelet posts node status to master. Note: be cautious when changing the constant, it must work with nodeMonitorGracePeriod in nodecontroller. Default: 10s (default 10s)
...
```
After
```
kubelet -h
...
--node-status-update-frequency duration Specifies how often kubelet posts node status to master. Note: be cautious when changing the constant, it must work with nodeMonitorGracePeriod in nodecontroller. (default 10s)
...
```
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #
**Special notes for your reviewer**:
This PR doesn't delete some "hard-coded" default values because they are not explicitly initialized. We still need to hard-code them to give users friendly info.
```
--allow-privileged If true, allow containers to request privileged mode. [default=false]
```
**Release note**:

allow fallthrough handling from go-restful routes
This sets up the gorestful routes to fall through to a default handler and reorders the API to be ahead of the other endpoints. This makes it possible to cleanly support cases of "match, fail, try this other handler" which we'll need for API server composition.

copy pkg/util/logs to apiserver
This is a copy, not a move. API servers need to be able to init the logs, but so do clients. It would be weird to have the client-side commands depending on the server side logs utilities.
I updated all the server side references, but left the client-side ones.
@sttts @kubernetes/sig-api-machinery-pr-reviews acceptable?
