Move `apidocspath` keys in `service-config` under routes section

Is this a BUG REPORT or FEATURE REQUEST?

This is not a bug. It is more of a readability enhancement suggestion

What happened

In service-config.js file, the config looks like below

api: {
    enabled: true,
    API_TIMEOUT: 60 * 1000 // In miliseconds
  },
  apiDocsPath: {
    postmanSpecPath: `${process.cwd()}/`,
    swaggerSpecPath: `${process.cwd()}/`
  },
  routes: {
    enabled: true,
    routeFolderPath: path.join(__dirname, '../routes')
  },

routes section registers REST end-points with express and also used to generate swagger specs and postman scripts. apiDocsPath specifies the location to save these generated swagger specs and postman script.

What you expected to happen

A more more readable configuration setup could be

api: {
    enabled: true,
    API_TIMEOUT: 60 * 1000 // In miliseconds
  },
  routes: {
    enabled: true,
    routeFolderPath: path.join(__dirname, '../routes'),
    postmanSpecPath: `${process.cwd()}/`,
    swaggerSpecPath: `${process.cwd()}/`
  },
