Explore: Add range option to internal data links

[connorlindsey]

What is this feature?

Adds an optional range to internal data links and uses it in field overrides if present.

Why do we need this feature?

The app o11y plugin links from a dashboard in the plugin to logs in Explore and needs a way to keep the time range the same. This will let us add the time range to the internal link config like so:

errorField.config = {
  ...errorField.config,
  unit: 'string',
  links: [
    {
      title: 'Logs',
      url: '',
      targetBlank: true,
      internal: {
        datasourceUid: lokiDs.uid,
        datasourceName: lokiDs.name,
        range: ctx.timeRange,
        query: {
          refId: '',
          expr: `{app="${ctx.appName}"} |~ "\${__value.raw}"`,
          queryType: 'range',
        },
      },
    },
  ],
};

Relates to https://github.com/grafana/app-o11y-kwl/issues/174

sounds reasonable to me 👍

Is it the same range as in the panel? If yes, could we pass the range from PanelQueryRunner? e.g.:

 series: applyFieldOverrides({
+    timeRange: data.timeRange,
     timeZone: data.request?.timezone ?? 'browser',
     data: processedData.series,
     ...fieldConfig!,
   }),

And later pass the range to getLinksSupplier.

This way it could work for any data link, without a need to pass the range in the config. Not sure if that would work for your use case.

Yeah, it is the same time range although the plugin uses the PanelRenderer which calls useFieldOverrides and doesn't run PanelQueryRunner, so I don't think that'd work for our situation. Maybe scenes will fix this out of the box.
