66713f69af embed: fix nil pointer dereference when stopServer 
Since v3.4.25, ETCD server introduces http-only urls flag to expose
gRPC-only endpoints. When user enables this feature, the stopServer will
panic during terminating. If the server is leader, it won't have chance
to transfer the leadership.

```

8dc1244179 server: Add --listen-client-http-urls flag to allow running grpc server separate from http server 
Difference in load configuration for watch delay tests show how huge the
impact is. Even with random write scheduler grpc under http
server can only handle 500 KB with 2 seconds delay. On the other hand,
separate grpc server easily hits 10, 100 or even 1000 MB within 100 miliseconds.

Priority write scheduler that was used in most previous releases
is far worse than random one.

Tests configured to only 5 MB to avoid flakes and taking too long to fill
etcd.

8f4735dfd4 server: Require either cluster version v3.6 or --experimental-enable-lease-checkpoint-persist to persist lease remainingTTL 
To avoid inconsistant behavior during cluster upgrade we are feature
gating persistance behind cluster version. This should ensure that
all cluster members are upgraded to v3.6 before changing behavior.

To allow backporting this fix to v3.5 we are also introducing flag
--experimental-enable-lease-checkpoint-persist that will allow for
smooth upgrade in v3.5 clusters with this feature enabled.

041b9069a2 *: configure server logger 
- Add/Document "logger" to support structured logging.
  - This makes functional tests run easier, since zap logger
    provides built-in log redirect to files.
  - "etcd --logger-option=zap" to enable structured logging.
- Current "capnslog" will still be used as "default".
  - We may switch the default or deprecate "capnslog" in v3.5.
  - Either way, will clearly be documented.
