Breaking changes

The workspaces() template variable, mainly for use with Azure Monitor Logs, has been changed to return resource URIs instead of Log Analytics Workspaces GUIDs. This should not impact Azure Monitor Logs queries, but if the variables are being used in other data sources which expect a Workspace GUID may no longer be compatible.

Custom template variables used in the workspace or resource field in Azure Monitor Logs queries should resolve to an Azure Resource URI in the format /subscriptions/{guid}/resourceGroups/{resource-group-name}/{resource-provider-namespace}/{resource-type}/{resource-name} Issue #34445

Removes support for deprecated backend plugin protocol (v1) including usage of github.com/grafana/grafana-plugin-model.
