# What this PR does
- update `slackclient` dependency to latest version. The version we were
using was 5 years old 😲
- first followed the v2 migration guide
[here](https://github.com/slackapi/python-slack-sdk/wiki/Migrating-to-2.x)
followed by the v3 migration guide
[here](https://slack.dev/python-slack-sdk/v3-migration/). The main
changes were:
- The PyPI project was renamed from `slackclient` to `slack_sdk`
- it is discouraged/harder to call `api_call` and encouraged to call the
helper methods (ex. `chat_postMessage`;
[note](https://github.com/slackapi/python-slack-sdk/wiki/Migrating-to-2.x#web-client-api-changes)
in migration guide docs)
- In 1.x, a failed api call would return the error payload to you and
have you handle the error. In 2.x, a failed api call will throw an
exception. To handle this in your code, you will have to wrap api calls
with a try except block. Since we overload `WebClient.api_call` this was
an easy change and only required a one line change
- remove `apps.slack.slack_client.slack_server.SlackClientServer` class.
The new version of `slack_sdk` handles the case that we needed to
overload for in the first place.
- merged `apps/slack/slack_client/slack_client.py` and
`apps/slack/slack_client/exceptions.py` into `apps/slack/client.py`

# What this PR does
Remove
[`apps.get_model`](https://docs.djangoproject.com/en/3.2/ref/applications/#django.apps.apps.get_model)
invocations and use inline `import` statements in places where models
are imported within functions/methods to avoid circular imports.
I believe `import` statements are more appropriate for most use cases as
they allow for better static code analysis & formatting, and solve the
issue of circular imports without being unnecessarily dynamic as
`apps.get_model`. With `import` statements, it's possible to:
- Jump to model definitions in most IDEs
- Automatically sort inline imports with `isort`
- Find import errors faster/easier (most IDEs highlight broken imports)
- Have more consistency across regular & inline imports when importing
models
This PR also adds a flake8 rule to ban imports of `django.apps.apps`, so
it's harder to use `apps.get_model` by mistake (it's possible to ignore
this rule by using `# noqa: I251`). The rule is not enforced on
directories with migration files, because `apps.get_model` is often used
to get a historical state of a model, which is useful when writing
migrations ([see this SO answer for more
details](https://stackoverflow.com/a/37769213)). So `apps.get_model` is
considered OK in migrations (even necessary in some cases).

# What this PR does
On notifying about shifts change in slack we don't check whether
organization was deleted. This PR excludes schedules from deleted
organizations from shift notification list

# What this PR does
- Adds [`mypy` static type checking](https://mypy-lang.org/) to our CI
pipeline. Currently there is still a **ton** of errors being returned by
the tool, as we'll need to fix pre-existing errors. I think we can
slowly chip away at these errors in small PRs, doing them all in one
large PR is likely very risky.
- Also, this PR starts chipping away at one of the main type errors that
we have which is accessing the `datetime` class (from the `datetime`
library) or `timedelta` function on the `django.utils.timezone` module.
Basically we should be instead accessing these two objects from the
native `datetime` module. This makes sense because the [`__all__`
attribute](https://github.com/django/django/blob/main/django/utils/timezone.py#L14-L30)
in `django.utils.timezone` does not re-export `datetime` or `timedelta`.
- splits `engine` dependencies out into `requirements.txt` and
`requirements-dev.txt`

Before this change, a diff ical check (which happens with frequency with
imported ical), particularly with overrides in an API/terraform schedule
would trigger unexpected slack notifications because the prev vs current
ical comparison will flag a diff, but when comparing current and
previous shifts, `current_shifts` will have the shift in progress while
the `prev_shifts` calculated from the overrides-only diff will most of
the time be empty (unless you set/change an override at current time).
Simplified the checks to always compare previous current shifts (ie. the
ones in the schedule from the DB) vs the recalculated ones using the
(refreshed) ical data from the schedule.
This should fix task error as seen in logs, trying to parse an empty
string as ical value:
```
Task apps.schedules.tasks.refresh_ical_files.refresh_ical_file[] raised unexpected: ValueError("Found no components where exactly one is required: ''")
```
* New ical comparision func
* Add support for field `sequence` for custom on-call shifts
* Fix ical comparison
* New ical comparision func 2
* fix
* Revert "Add support for field `sequence` for custom on-call shifts"
This reverts commit b7b18d5a
