Allow automatic dependency injection

[bsak2003]

We need a way to simplify the Dependency Injection process, such as attribute [Inject] to automatically inject dependencies.

Also, services loaded in this way should have deactivation switch ('enabled' property), like:

"Services": {
  "SampleService": {
    "enabled": true,
    "property": "value"
  }
}

Old idea

This interface will allow DependencyInjection to automatically invoke all compatible DependencyInjectors.

public interface IDependencyInjector
{
    public void Add(IServiceCollection services, IConfiguration configuration);
    public void Use(IApplicationBuilder app, IConfiguration configuration);
}
