--------------------------------

             Summary: scala api createLocalEnvironment() function add default Configuration parameter
                 Key: FLINK-4669
                 URL: https://issues.apache.org/jira/browse/FLINK-4669
             Project: Flink
          Issue Type: Improvement
          Components: Streaming
            Reporter: shijinkui


scala program can't direct use createLocalEnvironment with custom Configure object.

such as I want to start web server in local mode, I will do such as:

```
// set up execution environment
val conf = new Configuration
conf.setBoolean(ConfigConstants.LOCAL_START_WEBSERVER, true)
conf.setInteger(ConfigConstants.JOB_MANAGER_WEB_PORT_KEY, ConfigConstants.DEFAULT_JOB_MANAGER_WEB_FRONTEND_PORT)
val env = new org.apache.flink.streaming.api.scala.StreamExecutionEnvironment(
  org.apache.flink.streaming.api.environment.StreamExecutionEnvironment.createLocalEnvironment(2, conf)
)
```

so we need createLocalEnvironment function have a config parameter
