Implement semaphore synchronization to prevent concurrent modifications of InstanceStatus

- Added a Semaphore to control concurrent access to InstanceStatus modifications.
- Modified EurekaClientConfigurationRefresher to acquire the semaphore before performing deregister and register operations.
- Modified DiscoveryClientConfiguration to acquire the semaphore before performing refreshInstanceInfo operations.
- Ensured the semaphore is released in a finally block to handle exceptions properly.

This change addresses the issue of concurrent modifications of InstanceStatus, ensuring that only one thread can modify the status at a time.
