Support for selecting a specific service provider during debugging

[tonycody]

When in a development environment, services are registered in the registry. The same project, the same service, multiple coworkers start the project, multiple service providers exist, and at the moment the service is requested, coworker A may expect the request to be for his own machine.

This scenario is currently not supported, you need to add a service provider IP selection item in the debug page, when you select a provider request, request the service provider's machine. When not selected, the load is balanced by default.
