Improve config JSON readability and composability

[blizzardc0der]

Description

Currently, I've improved the readability and composability of the JSON file by applying the changes mentioned in the issue.

We now have "name" and "config" field for an individual store and scheduler JSON for setting its name and its configurations.
And "stores" and "schedulers" field now accepts array instead of map.

Fixes #834

instead of config, we should be using options. The whole file is a config.

Well, @allada wanted that to be config instead of options.
See this discussion below.
#834

What would be the correct wording for that?
I want you to clear that. Thanks. cc: @allada , @MarcusSorealheis
