Pipe: Fixed the OPC UA client connection problem

[Caideyipi]

Description

The OPC clients may flood to the receiver when there are multiple regions. However, the OPC Server has rates limit and will reject client connections if they're too often. Thus, I:

1. Reused the client pointing to the same receiver on the same dataNode.
2. Set retry seconds and will keep retry per second for rate limit at server.
