Description

Currently although the api presents itself as triggering different celery tasks via the type parameter it actually use the same celery task under the hood. This has lead to bad coding practices and unorganised code as it's easy to bodge together additional functionality without focussing on structuring the code appropriately.

This PR aims to fix this by separating known tasks out. This should have no impact on users of the API and is purely to improve code organisation
