`--kubelet-cgroups` and `--system-cgroups` respectively.
Updated `--runtime-container` to `--runtime-cgroups`.
Cleaned up most of the kubelet code that consumes these flags to match
the flag name changes.

* Metrics will not be expose until they are hooked up to a handler
* Metrics are not cached and expose a dos vector, this must be fixed before release or the stats should not be exposed through an api endpoint
Add a `/stats/summary` endpoint to the kubelet which will return an
empty Summary{} struct (json formatted), as a summary API
placeholder. Once the next cAdvisor release is vendored, the summary
API will be filled in.
Changes include:
- Moving stats serving & routes to pkg/kubelet/server/stats/handler.go
- Managing the routes with restful.WebService, rather than manual
parsing
- Misc cleanup
These changes will make adding the new routes for /stats/summary more
manageable.
- Sample is now the toplevel struct, so all child structs have the same
timestamp
- Removed FilesystemStats. There are more discussions needed
wrt. volumes and disk accounting, so this will be added in a follow
up PR
- Removed Options. The most recent sample will be returned.
This API has been discussed ad nauseam across several forums, and this
API represents the latest conclusion. In summary, we will provide this
API as temporary solution for providing the new stats required for 1.2.
In the longterm this API will be split into "essential" stats, which
will be provided by a first-party API served through the kubelet, and
"non-essential" (monitoring) stats, which will be provided by a 3rd
party API served from a pod.
