Data Prep tab should indicate which connection of a particular type is open

Currently each tab tells you that the connection is of type "Local File Upload", or "File System" or "Database", or "Kafka", or "S3", or "GCS". In the case of the first two, this is ok. However, for the latter 4, there can be multiple connections of each type. When a tab is open, a user will have no idea which of the connections the tab is from. The tab should indicate the name of the connection, in addition to its type, which it already indicates.
