For FLINK-6912:
There are three implementations of RichFunction that actually use
the Configuration parameter in RichFunction#open:
1. ContinuousFileMonitoringFunction#open: It uses the configuration
to configure the FileInputFormat. [1]
2. OutputFormatSinkFunction#open: It uses the configuration
to configure the OutputFormat. [2]
3. InputFormatSourceFunction#open: It uses the configuration
to configure the InputFormat. [3]
And none of them should have any effect since the configuration is empty.
