Currently querying databases rely on establishing connection to one toolsdb and one wikidb on //analytics//. Soon this scheme [[ https://wikitech.wikimedia.org/wiki/News/Wiki_Replicas_2020_Redesign | will stop working ]], so in February we have to make the migration from current setup to the updated one.
Also, this affects command line arguments and establishing connection. Might make sense to create shell script or use python + some config file to open all the ports instead of typing so many arguments.
### Subtasks
- [ ] Create updatable mapping of current shard location (looks like have to use noc, as meta_p is not updated when shards are moving)
- [ ] Write helper script for opening necessary amount of ports directly from python
- [ ] How to request which ports to use? Maybe some user-config file will do?
