Add is_zephyr to the Stream model. Add this field to the Stream model will prevent us from having to look at realm data for several types of stream operations, which can be prone to either doing extra database lookups or making our cached data bloated. Going forward, we'll set stream.is_zephyr to True whenever the realm's string id is "zephyr".

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.
