793218ed2b update the confstate before sending snapshot 
When there is a `raftpb.EntryConfChange` after creating the snapshot,
then the confState included in the snapshot is out of date. so We need
to update the confState before sending a snapshot to a follower.

etcd.service: Support Graceful Reboot for AIO Node 
Currently our sample systemd service file `contrib/systemd/etcd.service`
have startup/shutdown dependency as below:

    [Unit]
    After=network.target

For some rare condition, e.g. bare matel deployment with slow network
startup, IP could not be assigned e arly enough before etcd default
`ETCD_HEARTBEAT_INTERVAL="100"` and `ETCD_ELECTION_TIMEOUT="1000"` get
timeouted, after graceful system reboot.

This cause etcd false negative classify itself use unhealthy, therefore
stop rejoining the remaining online cluster members.

This PR introduce:

  - `etcd.service`: Ensure startup after `network-online.target` and
    `time-sync.target`, so effective network connectivity and synced
    time is available.

The logic is concept proof by
<https://github.com/alvistack/ansible-role-etcd/tree/develop>; also
works as expected with Ceph + Kubernetes deployment by
<https://github.com/alvistack/ansible-collection-kubernetes/tree/develop>.
No more deadlock happened during graceful system reboot, both AIO
single/multiple node with loopback mount.

Also see:
