Improve etcd-version-monitor metrics proxying, add etcd 3.1 gprc metr…
Partially addresses https://github.com/kubernetes/kubernetes/issues/56869:
- Fix `etcd-version-monitor` to support etcd 3.1: Add support for the etcd 3.1+ [go-grpc-prometheus](https://github.com/grpc-ecosystem/go-grpc-prometheus) metrics format, which backward incompatibly replaces the 3.0 legacy grpc metric format. Expose the go-grpc-prometheus metrics both in the 3.1 format and in the 3.0 format so systems consuming `etcd-version-monitor` metrics have a clean, simple upgrade path.
- Expose *all* etcd metrics by default, making this a one stop shop for all etcd metrics.
- Expose grpc request latency histogram metrics (`grpc_server_handling_seconds` from [go-grpc-prometheus](https://github.com/grpc-ecosystem/go-grpc-prometheus) metrics format). Rewrite etcd 3.0 legacy metric for latency histograms to the etcd 3.1+ `go-grpc-prometheus` format so there is a single format exported for all etcd versions.
etcd 3.0 to 3.1 upgrade path: Continue to use the `etcd_grpc_requests_total`. Once the upgrade is complete and all etcd nodes are running 3.1, migrate to the `grpc_server_handled_total` metric at your leisure.
This PR reorganizes the code substantially. Previously, the code to proxy etcd metrics was hard coded and limited to a single counter metric. This has been entirely replaced with code that generically filters, rewrites proxied etcd metrics and then aggregates them with custom metrics such as the etcd version metric.

We shouldn't upgrade etcd without first warning the user that some etcd
version transitions can't be undone. We don't know what version the user
currently has, so we require either an explicit version and image, or an
interactive acknowledgement of this caveat.
This is modeled after the STORAGE_MEDIA_TYPE prompt just above.
