perf: enhance provider management with reload locking and logging (#3793)

- Introduced a reload lock to prevent concurrent reloads of providers.
- Added logging to indicate when a provider is disabled and when providers are being synchronized with the configuration.
- Refactored the reload method to improve clarity and maintainability.
