Support for Groups in connection file?

[stevenproctor]

Thanks for the plugin, it is great!

I was adding connections, and was wondering if there is the chance that grouping of connections might be supported.

Not sure if this is already a feature that is supported, as the JSON payload in the connections file looks pretty flat.

I was checking in, as it might be useful to be able to setup groups, or even a hierarchy, of connection strings.

Right now, I am doing DB Connection naming, and re-arranging JSON in the connections file to get things "grouped" by arranging the entries in the JSON list, and wanted to see it having nested JSON was a possibility.

I was wondering if there is already support, or it might be straightforward enough to add, to get something like:

 App 1
  - Dev
    - instance 1
    - ...
    - instance n
  - Prod
    - instance 1
    - ...
    - instance m
  App 2
  - Dev
    - instance 1
    - ...
    - instance x
  - Prod
    - instance 1
    - ...
    - instance y

Simply grouping the connections by something, while still adding them as before, should be fairly straightforward. Figuring out database name like mentioned in https://github.com/kristijanhusak/vim-dadbod-ui/issues/123 would be a bigger effort.
