Very useful addition!
Small implementation issue: We're trying to be less reliant on angular services, and hence want to prevent their leakage into plugin submodules. Could you add a function to the datasource instead that returns {start, end}

this.labelQueryCache[expr] = response.data.data.result; | ||
return response.data.data.result; | ||
let range = this.datasource.getTimeRange(); |

LGTM. Thanks for your contribution!
instant query doesn't return all label name/value of dashboard time range.
So, change to use series API.
