Import shapes with new management command

[jeancochrane]

Overview

Following the changes in datamade/django-councilmatic#249, create a data directory to store Post shapes locally, and use the new import_shapes management command to load those shapes into the database.

Testing instructions

Test the Makefile

• Confirm that you can recreate the data file:
  • cd data
  • make clean
  • make

Test the import_shapes command

• Check out the branch from Create management command for importing Post shapes django-councilmatic#249 to your local django-councilmatic instance, and make sure it's installed to the chi-councilmatic virtualenv with pip install -e /path/to/django-councilmatic
• Run migrations: python manage.py migrate
• Import the shapes: python manage.py import_shapes data/final/shapes/chicago_shapes.json
• Run the development server: python manage.py runserver
• Navigate to http://localhost:8000/council-members/ and confirm that the boundaries load as expected
• Navigate to a council member detail page (e.g. http://localhost:8000/person/la-spata-daniel-bca2038dd957/) and confirm that the boundaries load as expected

I adapted this function from https://github.com/datamade/django-councilmatic/blob/5387ae85ea289b22c4e0ea566fa89a1c43155ed0/councilmatic_core/management/commands/import_data.py#L3250-L3261, including the docstring. I'm not actually sure whether the docstring accurately represents what's going on in the function -- it seems to me that the method is simply a thin wrapper around requests to make sure that it A) uses a session and B) raises errors from non-200 status codes -- but the docstring seems to perhaps be communicating an aspect of the OCD API that is useful to know.

I think we don't want this. Let's just get https://data.cityofchicago.org/Facilities-Geographic-Boundaries/Boundaries-Wards-2015-/sp34-6z76 and get into the right shape (see discussion in the other PR)
