Alive nodes can't send last will messages to subscribed clients when there is one node killed in the cluster.

Environment

• OS: centos 7
• Erlang/OTP:
• EMQ: 2.3.1

I have a EMQTT cluster with 2 machine，nodeA and nodeB.
I have 1 client named device publish last will messages device/will，payload offline text，and it is connected to nodeA。
I have 1 client named receiver subscribe device/will， and it is connected to nodeB.

Then
1、When I killed device，receiver can receive the last will message offline.
2、When I killed nodeA，receiver can't receive the device last will message offline, then it means that the receiver still think the device would be online.
The nodeB should reload the nodeA clients status when nodeA is dead, but it didn't do it. If I must use last will messages, what can I do to resolve this issue?

For now, emqx does not support to migrate or replicate sessions between different nodes. We'll support it in the future. Anyway, thanks for your feedback.
