# 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
This PR cleanup ScenarioStep. It's needed to simplify moving Slack to
the messaging backends in future.
1. Introduce AlertGroupSlackService to move logic from ScenarioStep.
Also it allowed to get rid of importing ScenarioSteps in the code not
related to processing of slack callbacks.
2. Remove tags from ScenarioSteps, they are unused.
3. Remove ScenarioStep.dispatch method. It just was calling
ScenarioStep.process_scenario.
4. Remove "action" param from process_scenario, it was unused.
5. Remove creation of SlackActionRecord on handling SlackEvents. We are
not using it, but it generates INSERT query on most of the user-slack
interactions.
6. Remove "random_prefix_for_routing" from ScenarioStep, it was unused.
