Ability to specify Redis DSN from ENV (i.e. add data binding picker)

Ability to specify Redis DSN from ENV
i.e. add data binding picker

P.S.: DSN is the formal name for that Redis URL

Edit: It seems server-side support also needs to be added, to parse the expression (NodeJS)

It does not work from the UI, but can be done directly in the config.json file.
Have been using it for a couple of years now.

An extract of my ENV:

{
  "debug": "{{$_ENV.DEBUG_MODE == 1}}",
  "cron": "{{$_ENV.RUN_CRON == 1}}",
  "secret": "{{$_ENV.WAPPLER_SECRET}}",
  "redis": "{{$_ENV.REDIS_URL}}",
}

Thanks, I didn't know this worked - I checked the source-code and couldn't find any obvious expression parsing
