Add possibility of opening additional ports for Local Mode #4025
Description
Describe the feature you'd like
Currently Local Mode does not allow opening any additional ports. This is problematic, since I can't connect to any databases, which renders some processors, e.g. PySparkProcessor, quite useless for me.
How would this feature be used? Please describe.
Pass additional arguments to LocalSession configuration, with list of ports to expose, e.g. 9200:9200, so that it will be translated to config ports: 9200:9200.
