WIP: [ISSUE-708] Extract interface from Microservices

[eutkin]

Modification sketches for DI extraction to a separate module.

Sample plan:

1. Create new interface for Microservices.
2. Create new interface for ServiceProvider ([Microservices, Mono<Collection<ServiceInfo>>]) for lazy services initialization. For example, Spring:

   microservices -> {
     var appContext = new GenericApplicationContext();
     // setup beans
     return Mono.defer(() -> 
   			appContext.getBeansByAnnotation(Service.class));
   }

3. Replace service instance to service instance supplier (for lazy) and service interface with @Service (as Class<?>) in ServiceInfo.
4. Change method register, method invoker (linked change set of ServiceInfo)
5. ???
6. Profit
