Enabling/disabling new generators per instance

[sstenchlak]

We are constantly adding new generators, forcing us to disable them explicitly in the production instance. However, it makes sense to have generators on by default in a test instance.

The default behavior of each generator for the given instance can be configured (see backend service config), but this configuration is per generator and hence needs to be modified for every new generator.

Therefore, we should introduce a new option, whether all generators are on by default and must be explicitly turned off (in the configuration) or vice versa.

Hi @jakubklimek, to disable all generators by default, add into services\backend\main.config.js configuration object following:

{
    configuration: {
        "data-specification": {
            generatorsEnabledByDefault: false,
            useGenerators: {
                json: true,
                plantUML: true,
                respec: true,
                // jsonExample: true,
                // xml: true,
                // csv: true,
                // sparql: true,
                // shacl: true,
                // shex: true,
                // openapi: true,
            }
        }
    }
}
