[3.3] Retry connect to provider server by catching ClosedChannelException

[zrlw]

What is the purpose of the change?

try to fix #15191
@AlbumenJ

... catch such exception and retry automatically. In the future, maybe 3.4, we can remove all the support of netty3 anymore. It is important to prevent importing surprising changes in minor release.
