Related to https://github.com/grafana/support-escalations/issues/13670
Given a payload like this:
```
{
"Sometime": "1730893740"
}
```
the following template expression:
`{{ payload.Sometime | int | timestamp_to_datetime }}`
will render as:
`2024-11-06 11:49:00`
# What this PR does
If an OnCall template needs to contain a date relative to a date in the
alert response, currently there is no way for the template to add or
subtract time from a parsed date.
This PR adds a function that allows a time-window (e.g., 1s, 5m, 6h, 7d,
2w) to be converted into a Python timedelta, which can then be added or
subtracted from a datetime. An example usage might be:
```
{% set delta = alert.timeWindow | timedeltaparse %}
{% set time = alert.startsAt | iso8601_to_time - delta | datetimeformat('%s') %}
```

# What this PR does
Jinja2 filter to parse strings into datetime objects. Previously, only a
limited set of strings could be parsed into datetime objects
([datetime_re](https://docs.djangoproject.com/en/2.2/_modules/django/utils/dateparse/)).
The addition of this filter allows for strings of any format to be
converted into datetime.

# What this PR does
This PR adds support for routing alerts based on labels.
https://www.loom.com/share/4401de6e3c4945d5b8961fe43ee373c9
Additionally:
- improve the typing around the `get_object` method that is inherited by
[`PublicPrimaryKeyMixin.get_object`](https://github.com/grafana/oncall/blob/dev/engine/common/api_helpers/mixins.py#L153)
in most of our models. `PublicPrimaryKeyMixin` is generic, so it can be
more strongly typed when it is being subclassed, which results in better
typing of the `get_object` method in child classes
- I decided to do this because I started looking into this task via the
[`AlertReceiveChannelView.send_demo_alert`
method/endpoint](https://github.com/grafana/oncall/blob/dev/engine/apps/api/views/alert_receive_channel.py#L242).
Within that method, `instance` is not typed because the inherited
`get_object` method is not typed.. I digress 😄
- improve typing around `Alert.create` and
`apps.integrations.tasks.create_alert` functions
- make `Alert.render_group_data` more DRY by extracting some logic out
into `Alert._apply_jinja_template_to_alert_payload_and_labels`
- deduplicate the logic of `value.strip().lower() in ["1", "true",
"ok"]` into a shared function,
`common.jinja_templater.apply_jinja_template.templated_value_is_truthy`

# What this PR does
Add an additional jinja2 template helper filter to convert a timezone
aware datetime to a different timezone.
## Which issue(s) this PR fixes
Alert payloads that originate from different time zones may include
timestamps having a local time offset. This filter enables
standardization of timestamp timezones.

# What this PR does
This PR adds new API endpoints for migrating routes from regex format to
jinja2 format. The changes include the following:
* `filtering_term_as_jinja2` field to GET `channels_filters` endpoint
* A POST endpoint
`channel_filters/ABCDEF123/convert_from_regex_to_jinja2/` for migrating
routes to jinja2 format.
These new endpoints will allow users to preview and migrate their
existing regex routes to the more flexible and maintainable jinja2
format.
Check the screenshot where this endpoints will be used
