For ObjectMeta pruning, we round trip through marshalling and
unmarshalling. If the ObjectMeta contained any strings with "" (or other
fields with empty values) _and_ the respective fields are omitempty,
those fields will be lost in the round trip process.
This makes ObjectMeta after the no-op write different from the one
before the write.
Resource version is incremented every time data is written to etcd.
Writes to etcd short-circuit if the bytes being written are identical
to the bytes already present. So this ends up incrementing the
resourceVersion even on no-op writes.
The zero values are set in BeforeCreate and BeforeUpdate. This commit
updates BeforeUpdate such that zero values are only set when the
object does not have a zero value for the respective field.

Fail container start if its requested device plugin resource is unknown.

ObjectMeta has fields with omitempty json tags. This means that when
the fields have zero values, they should not be persisted in the object.
Before this commit, some of the metadata accessors for unstructured
objects did not respect these semantics i.e they would persist a field
even if it had a zero value.
This commit updates the accessors so that the field is removed from the
unstructured object map if it contains a zero value.

Use sync.map to scale equiv class cache better
**What this PR does / why we need it**:
Change the current lock in first level ecache into `sync.Map`, which is known for scaling better than `sync. Mutex ` on machines with >8 CPUs
ref: https://golang.org/pkg/sync/#Map
And the code is much cleaner in this way.
5k Nodes, 10k Pods benchmark with ecache enabled in 64 cores VM:
```bash
// before
BenchmarkScheduling/5000Nodes/0Pods-64 10000 17550089 ns/op
// after
BenchmarkScheduling/5000Nodes/0Pods-64 10000 16975098 ns/op
```
Comparing to current implementation, the improvement after this change is noticeable, and the test is stable in 8, 16, 64 cores VM.
**Special notes for your reviewer**:
**Release note**:
```release-note
Use sync.map to scale ecache better

Wait for Available in PV protection test
**What this PR does / why we need it**:
Just after creating a PV, its phase is "Pending" and its finalizers
doesn't contain "kubernetes.io/pv-protection". If the e2e test performs
so faster than the target k8s cluster, the test fails because the PV is
not ready. This adds WaitForPersistentVolumePhase() for waiting the
phase "Available" to avoid such situation.

change TRUNCATED to DATA+OMITTED in kubectl config view
**What this PR does / why we need it**:
Based on the discussion in #61573, this PR switches the replacement text for CA certificate data and client certificates and secrets printed using `kubectl config view`. Currently, `REDACTED` is used, which might give a false impression that the data is a secret (which is not true for the public certificates).
This PR changes `REDACTED` to `DATA+OMITTED`. The printed string is the base64 encoded string on the byte stream. Some trickery is involved to print a readable string (refer to [this comment](https://github.com/kubernetes/kubernetes/pull/66023/files#diff-aec000ca3f293c94dcd99b4a9d1c5c3cL86) for more info).
**Which issue(s) this PR fixes**:
Fixes#61573
**Special notes for your reviewer**:
**Release note**:
```release-note
Switched certificate data replacement from "REDACTED" to "DATA+OMITTED"
```
