(v3.0.9) - New Sinergym preconfigured environments definition

[AlejandroCN7]

Description

As we introduce more buildings officially into the tool, it becomes more complex to define the default spaces. Even if we want to overwrite the spaces of a predefined environment, this can be very extensive in the code.

In this PR, it is proposed to migrate spaces, variables and reward definition for pre-configured environments to JSON files, one per each building model type. These JSON will have all the configuration required for continuous and discrete environments (except action mapping functions for discrete environments, since these functions are not pretty in JSON format).
