Version bump to etcd v3.2.13, grpc v1.7.5

Reapply kubernetes/kubernetes#57160 but with etcd 3.2.13, which includes etcd-io/etcd#9047 to fix kubernetes/kubernetes#51099.

We need to scalability test this PR before merging it since the previous attempt to version bump to grpc v1.7+ resulted in a scalability test failure after the PR was merged to master, and we don't want to repeat that. No, no we don't.

Thanks @gyuho for fixing the etcd grpc issue and releasing etcd-3.2.13 on short notice.

**Release note**:

```release-note
Upgrade to etcd client 3.2.13 and grpc 1.7.5 to improve HA etcd cluster stability.
```
