Hannah Wolfe 51ac3f6532 Refactor to using pipeline for the API
refs #2758

- Post, Tag & User API methods are refactored to use pipeline
- Each functional code block is a named task function
- Each function takes options, manipulates it, and returns options back
- Tasks like permissions can reject if they don't pass, causing the pipeline to fail
- Tasks like validating and converting options might be abstracted out into utils - the same for each endpoint
- Tasks like the data call can be extremely complex if needs be (like for some user endpoints)
- Option validation is mostly factored out to utils
- Option conversion is factored out to utils
- API utils have 100% test coverage
- Minor updates to inline docs, more to do here
