> The configuration is split into two parts, one defining the parameters of the test
> run and the other defining the topology to be used.
> 
> The format of the configuration is YAML. It is validated according to a json
> schema which also servers as detailed documentation of the various
> configuration fields. This means that the complete set of allowed values are tied
> to the schema as a source of truth. This enables making changes to parts of DTS
> that interface with config files without a high risk of breaking someone's
> configuration.
> 
> This configuration system uses immutable objects to represent the configuration,
> making IDE/LSP autocomplete work properly.
> 
> There are two ways to specify the configuration file path, an environment
> variable or a command line argument, applied in that order.
