# What this PR does

`apps.alerts.tasks.delete_alert_group.delete_alert_group` when hitting
Slack ratelimits
- remove Slack messages from the DB as soon as they are deleted from
Slack, so the tasks are not retrying perpetually

# What this PR does
Make sure that Slack user groups are not getting updated for deleted
orgs.
Without this change, there could be issues with backends in multiple
clusters trying to update a single Slack user group after migrating an
org to another cluster (organizations get soft deleted from the original
cluster after migration).

# 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`

When calculating on-call load, if an involved shift extends outside the
requested time span you can get unexpected results. Truncate the
returned events times to keep the details for the specified start/end
dates.

# What this PR does
Make descriptions consistent for the `STEP_NOTIFY_IF_TIME` escalation
step (my [initial
assumption](https://github.com/grafana/oncall/pull/2729#discussion_r1281929984)
seems to be wrong and this can confuse users).

# What this PR does
If the same heartbeat is requested at a high rate it can create lock
contention when updating the timestamp in the DB. Moving to always run
update in task should free up the connection on the API server faster,
although the task might still see some lock wait time.
