* Fixes Readiness Check for statefulsets using partitioned rolling update.
Fixes#11773
This change updates readiness check in ready.go to correctly
account for statefulsets that are utilizing a partitioned upgrade.
These statefulsets only upgrade a subset of the managed pods with each call
to helm upgrade. This causes the upgrade to legitimately hit the condition where
sts.status.CurrentRevision != sts.Status.UpdateRevision which causes helm to mark
the upgrade has failed when in fact it is successful.
This change fixes that behavior to only check when partition is unspecified or 0.

Confirm that the current and updated revision numbers also match as part
of the readiness check. Add coverage for readiness scenarios where
StatefulSet status does not reflect the most recent generation of the
StatefulSet yet.
Also add additional logging around the sts transitions from non-ready to
ready.

The partition value can be greater than number of replicas, in that
case no pods are rolled out. The expectedReplicas becomes a negative
number.
https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/#partitions
In the cases where the update does not change anything in the pod
template, the updatedReplicas value from StatefulSet status remains
unchanged. Such updates can still set some partition value, and
UpdatedReplicas is always greater than expectedReplicas. Basically,
the StatefulSet is ready / rolled-out.
In both the above scenarios, providing `--wait` flag causes it to
timeout waiting indefinitely. Because updatedReplicas can never be
negative, or be equal to the expectedReplicas for the second case.
This commit handles both the scenarios by checking if UpdatedReplicas
is smaller than expectedReplicas. If it is, then the StatefulSet is
not ready yet.
Based on the code from kubectl rollout:
