Simplify Cumulus folder structure

[scisco]

• remove the cumulus folder altogether
• move cumulus/tasks to tasks folder at the root level
• move the tasks that are not converted to use CMA to tasks/.not_CMA_compliant
• update paths where necessary

I would call this header either Changed or Fixed. There's no Updated section defined at https://keepachangelog.com/en/1.0.0/#how.

I would call it Changed if there's any chance at all something could be depending on the original directory structure, and would make that a major version bump.

Otherwise I would call it Fixed.

Good point. Will update to "Changed". All the deployments should be using the tasks from npm so I don't expect anyone relying the folder structure.

It should be listed under Fixed. This is only important because if there's a Changed section under Unreleased then that's an indicator that the next release needs to be a major version bump.
