Refactor resources module

[matthewhegarty]

Problem

resources.py has grown to be a large module. I have moved 'declarative' code and and ResourceOptions into separate modules.

There are no functional changes in this PR.

Acceptance Criteria

• All existing tests pass

I am fine with this but would throw out using a subfolder called resources and placing the files in there as an option that might be easier to understand.

Hi Ryan

Thanks for reviewing, much appreciated.

I did think about using a subfolder. SQLAlchemy has a subfolder called ext that they put their declarative code into, however that name convention doesn't seem to apply here.

It does seem that since this code is helper code for resources.py it should be hidden away.

We could go with resources, but that then implies that resources.py should go in there as well, then presumably releated fields.py, instance_loaders.py etc, then we have a large change on our hands.

To keep things simple, I wonder if it is easier just to keep them in separate top level modules as in this PR. What do you think?

Yeah I was thinking the django models folder style route where you make a resources folder, then import everything into the init.py in that folder would make it so you didn't have to change anything - everything still imports from resources.

But there're definitely issues with that approach :)

Are you ok for me to merge as it is?

Yup, always something we can tackle later if desired and this is an improvement.
