ref(mypy): don't ignore missing imports by default (#486)

Now we explicitly ignore specific imports instead of a blanket ignore
on all missing types.

Upgraded databases and pytest to get their latest versions which include
types, for the rest we're ignoring them explicitly.
see #485

- arrow

  doesn't have types but we can replace it with std library calls

- requests_async

  deprecated in favor of httpx, so we'd need to upgrade to get types.
  The API of httpx is a little different as well.

- structlog

  doesn't have types currently

  hynek/structlog#165

- rure

  No stubs yet

  davidblewett/rure-python#23

- pytest_mock

  types recently added to the typeshed so we'll need to wait for the next
  release of mypy.

  pytest-dev/pytest-mock#152

- markdown_html_finder

  Wrapper around some Rust code. Needs stubs to be added.

  chdsbd/markdown-html-finder#5

- asyncio_redis

  We're using our own fork of it, but adding types would be rather manual.
  Granted we aren't using that much of the API surface.

  https://github.com/chdsbd/asyncio-redis

- zstandard

  No stubs yet, so we're ignoring for the time being

  indygreg/python-zstandard#120

- inflection

  Types, but I think they're misconfigured, once they're fixed we can
  unignore.

  jpvanhal/inflection#49

- django

  Need to setup django-stubs for this to work since django doesn't have
  any static types.

  https://github.com/TypedDjango/django-stubs

- dj_database_url

  Doesn't have any static types yet

  jazzband/dj-database-url#135

- responses

  No types yet

  getsentry/responses#339

- stripe

  Plan for types, but they don't exist currently

  stripe/stripe-python#650
