Enhancement request: Provide db_addr variable in "-r db" in Django

[CoolBlueSam]

Currently when calling run for django, you are able to specify the db_addr {"db_addr": ""}

However while initializing the db, you cannot do it unless you do it via run.sh script directly (as mentioned in the documentation). Should be easy to add support for this variable for -r db option as well.

Thanks for suggesting, sure we will add this option to the Benchpress command.
