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.
Removes the uniqueness constraint on RealmAlias.domain, and adds a function
can_add_alias that checks for uniqueness conditional on
settings.REALMS_HAVE_SUBDOMAINS.
