Make connection names unique?

[Khatskevich]

Suggestion

1. make connection names unique per the whole schema
2. change connection description format array[id]=value -> dict[name]=value

Motivation for (1)

1. In case we create types for connections (for example for nested arguments) GQL requires them to have unique names
2. Our accessor_general.build_connection_indexes relies on that. Here is a snippet from the function which may override index in case of connections from different collections to the collection have the same names.

            connection_indexes[c.destination_collection][c.name] = {            
                index_name = index_name,                                        
                connection_type = c.type,                                       
            }

Motivation for (2)

1. I suppose the format is easier to parse (for some features I have to do convert to that format by my own)
2. more native for schema description and looks closer to description of other elevents such as collections, schemas and indexes

It should be noted that (2) is proposal to change external API. But it does not lack of sense, though.
