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.
