Update bazelbuild/rules_go, kubernetes/repo-infra, and gazelle dependencies
**What this PR does / why we need it**: updates our bazelbuild/rules_go dependency in order to bump everything to go1.9.4. I'm separating this effort into two separate PRs, since updating rules_go requires a large cleanup, removing an attribute from most build rules.

This PR adds pod-level ephemeral storage metric into Summary API.
Pod-level ephemeral storage usage is the sum of all containers and local
ephemeral volume including EmptyDir (if not backed up by memory or
hugepages), configueMap, and downwardAPI.
assert.Contains() checks if its second argument (which is supposed to be
a single element) is contained in its first argument (which is supposed
to be a slice/map etc.) The third and following arguments are supposed
to be message and args for the output in case of failure.
Because of this bad form, a failure was hidden, the system container is
named "misc", not "system".

Skip system container cgroup stats if undefined
**What this PR does / why we need it**:
the kubelet /stats/summary endpoint tried to look up cgroup stats for containers that are not required. this polluted logs with messages about not finding stats for "" container. this pr skips cgroup stats if the cgroup name is not specified (they are optional anyway)
**Special notes for your reviewer**:
i think this was a regression from recent refactor.
**Release note**:
```release-note
NONE
```
For pod volumes that reference a PVC, add a PVCRef to the corresponding
volume stat. This allows metrics to be indexed/queried by PVC name
which is more user-friendly than Pod reference

Remove the status of the terminated containers in the summary endpoint
Ref: https://github.com/kubernetes/kubernetes/issues/47853
- When building summary, a container is considered to be terminated if it has an older creation time and no CPU instantaneous or memory RSS usage.
- We remove the terminated containers in the summary by grouping the containers with the same name in the same pod, sorting them in each group by creation time, and skipping the oldest ones with no usage in each group. Let me know if there's simpler way.
**Release note**:
```
None
```
