Feedback: navigating to another container feels like it involves more clicks than it should

[sevoku]

This is a comment from our feedback survey: navigating to another container feels like it involves more clicks than it should

Some ideas how to improve it:

1. We could add a new "Query Editor" node to containers here:
   
   which would simply open the query editor for the selected container, as it's done for the "Documents" node for Mongo.
2. The "Disconnect"/"Connect" buttons don't make much sense in our scenario, they're too technical:
   
   Instead we could have a dropdown with a list of all containers inside the parent database, or it could be a nested menu with databases and containers.
