analytics: Add table to keep track of fill state. Adds two simplifying assumptions to how we process analytics stats: * Sets the atomic unit of work to: a stat processed at an hour boundary. * For any given stat, only allows these atomic units of work to be processed in chronological order. Adds a table FillState that, for each stat, keeps track of the last unit of work that was processed.

python: Sort migrations/management command imports with isort. This is a preparatory commit for using isort for sorting all of our imports, merging changes to files where we can easily review the changes as something we're happy with. These are also files with relatively little active development, which means we don't expect much merge conflict risk from these changes.

models: Remove unused ModelReprMixin class. It appeared to be used as a base class in various Django migrations, but because it didn't define any model fields, it wasn't actually.
