• Consolidated all policies into openfl/component/aggregator/straggler_handling.py

@ishant162 , did you test for regression by raising a PR in OpenFL-Security?

This needs to be done @teoparvanov . We will feedback once it is done

This is a good improvement over the previous layout.

Most suggestions, though seem like nitpicks, have measurable changes on developers and users in the look-and-feel of the framework. Please take a look.

Folks, this PR is taking a little too long to merge. Can we try closing it this week?

Hi @MasterSkepticista,
I’ve verified the links by running the documentation locally. The straggler_handling module is now part of the openfl.component.aggregator module.

Note: The links to the source code for straggler handling policies are currently broken as they point to securefederatedai/openfl. Since the straggler_handling module has been moved under the aggregator module, I expect these links to work correctly once this PR is merged.
