Parse JSON values of environment variables

[roma-glushko]

It's not that uncommon to pass JSON in environment variables for complex data.

For example, If you deploy your stuff in a Kubernetes cluster using Helm and you have some additional logic that build together values of your env vars dynamically, chances are it will be convenient for you to leave these env var values as JSON strings.

Is this currently possible to parse an env variable as JSON of specific type like an array of strings e.g. ["http://url1", "http://url2"], or a struct?
