grpclog.SetLoggerV is not thread-safe and may only be called before code starts
using GRPC. Calling RunCustomEtcd multiple times, for example in
k8s.io/kubernetes/test/integration/apiserver.TestWatchCacheUpdatedByEtcd,
causes a data race:

Users can pass resources into `kubectl events` command via `--for` flag,
if they have desire to only get events for the resource they specify.
However, current `kubectl events` does not support passing fully qualified
names(e.g. `replicasets.apps`, `cronjobs.v1.batch`, etc.). This PR adds support
for this.
The newly added `MirrorPodWithGracePeriod when create a mirror pod and
the container runtime is temporarily down during pod termination` test
is currently flaking because in some cases when it is run there are
other pods from other tests that are still in progress of being
terminated. This results in the test failing because it asserts metrics
that assume that there is only one pod running on the node.
To fix the flake, prior to starting the test, verify that no pods exist
in the api server other then the newly created mirror pod.

this check needs to go after any mutations. After the mutating admission chain, rest.BeforeUpdate (which is responsible for reverting updates to immutable timestamp fields, among other things.) is called in the store.Update function. Without moving this check, it will be possible for an object to be written to etcd with only a change to its managed fields timestamp.

- handle ResourceVersion and Preconditions correctly
- handle DryRun option correctly

* Slightly changed pod spec to repro issue #116262
* Refactor test to ensure that the static pod is deleted even if the
test fails

We now get structured output using jsonpath for the
name and version fields of the node object and then
compare the outputs.
