a large number of akka remote logs

## Environment details:

centeos docker1.17

## Provide the expected results and outputs:

```
after the Controller starts, it prints a large number of logs related to akka remote.
consider adjusting the relevant log level?
```

## Provide the actual results and outputs:

```
Discoverd [1] contact points , confimed[1],which is less than the required[2] ,retrying
```

Start by reproducing Controller startup in the stated CentOS and Docker 1.17 environment and trace the `Discoverd [1] contact points` message associated with Akka remote. Identify where that message is emitted and determine the appropriate log-level change; done means startup no longer produces the excessive Akka remote logs while retaining useful diagnostics.
