The ng_alert_notification email template did not include templating for
linked or embedded images. This change updates that.
Additionally, this change supports embedding an image for each alert in
an email batch.
Fixes#50315
* optional custom description for OpsGenie
* custom title and message, tests
* update changelog
* check for empty / whitespace only strings
* truncate the title to 130 characters if needed
* unnecessary validation removed
* truncate title to 127 characters and add three dots
* Alerting: decapitalize log lines and use "err" as the key for errors
Found using (logger|log).(Warn|Debug|Info|Error)\([A-Z] and (logger|log).(Warn|Debug|Info|Error)\(.+"error"
The image file upload code as it is now simply doesn't work - it's
missing several important steps in the file upload process. There is
more information in the fixed issue as to the steps required.
After this change, screenshots will still be attached to slack messages
when external image storage is used with Grafana (an S3 bucket, for
example).
Fixes#50056
Tests that file bytes are correctly read from storage when an image is
available without a URL. Tests that not found and success cases are both
handled.
* Alerting: Do not include button in googlechat notification if URL invalid

Adds three functions:
`withStoredImages` iterates over a list of models.Alerts, extracting a stored image's data from storage, if available, and executing a user-provided function.
`withStoredImage` does this for an image attached to a specific alert.
`openImage` finds and opens an image file on disk.
Moves `store.Image` to `models.Image`
Simplifies `channels.ImageStore` interface and updates notifiers that use it to use the simpler methods.
Updates all pkg/alert/notifier/channels to use withStoredImage routines.
If an image token is present in an alert instance, the email notifier will attempt to find a public URL for the image token. If found, it will add that to the email as the `ImageLink` field. If only local file data is available, the notifier will attach the file to the outgoing email using the `EmbeddedImage` field.
Adds an array of image_urls to the OpsGenie details field in a message, if image urls are available.
```json
{
"message": "Alert with Images!",
"details": {
"image_urls": ["http://www.example.com"]
}
}
```
If there are screenshot images with URLs, they will be attached to the
Microsoft teams notification in the first sections, as a slice of image
objects.
This change extracts screenshot data from alert messages via a private annotation `__alertScreenshotToken__` and attaches a URL to a Slack message or uploads the data to an image upload endpoint if needed.
This change also implements a few foundational functions for use in other notifiers.
* Resolve merge conflicts
* Remove cruft from local exploration
* Move integration tests to intercept using new abstraction layer instead of channel
* Fix linter error after rebase
* add field for custom slack endpoint
* add test for using custom endpoint
* Update pkg/services/ngalert/notifier/channels/slack.go
