microservice-router-register

Provide:

• class MicroserviceRouterRegister to register microservice in microservice-router
• class loaderClass internal use only class. Help to load data from other service by provides option.
• function clientViaRouter(path, accessToken, callback) to access other microservices from microservice by url. accessToken is optional.
• function loaderMicroservice(method, jsonData, requestDetails, callback) implements callback.loader for microservice-cluster. Automatically load to requestDetails.name values from path myservice/:name/subservice
• function loaderByList(list, accessToken, callback) used by ws integration to make sure that accessToken has access to myservice/:name/subservice
