Update load balancer pool

Updates the specified load balancer pool with the provided changes.

Behavior:

• Simple fields (strings, numbers, booleans) will be updated if provided
• Complex objects (nested structures like members, health monitors, etc.) must be specified completely - partial updates are not supported for these objects
• Undefined fields will remain unchanged
• If no change is detected for a specific field compared to the current pool state, that field will be skipped
• If no changes are detected at all across all fields, no task will be created and an empty task list will be returned

Examples of complex objects that require full specification:

• Pool members: All member properties must be provided when updating members
• Health monitors: Complete health monitor configuration must be specified
• Session persistence: Full session persistence settings must be included
