SDK - Components - Added component properties to the task factory fun…

…ction

Problem: When the user loads component using the load_component function, the object they get back is a task factory function. Since it's a normal function object, the user cannot inspect any of the attributes of the component they just loaded (they can only see the name, description and input names). For example, the user cannot see the list of component outputs, the annotations etc.

This change fixes the issue by adding the original component properties to the function object.

Example usage:

```python
train_op = load_component_from_url(...)
print(train_op.outputs)
```
