Support /api/v1/parse_query API (Experimental)
Is your feature request related to a problem? Please describe. Dashboard tools, in this specific case perses, might relay on this prometheus API part to parse the query.
Describe the solution you'd like Query frontend should handle this part
Describe alternatives you've considered None
Additional context Yes, it's experimental, but we should implement it per https://www.hyrumslaw.com/ ;) https://prometheus.io/docs/prometheus/latest/querying/api/#parsing-a-promql-expressions-into-a-abstract-syntax-tree-ast
The treeview feature is enabled with this https://github.com/perses/perses/issues/2420#issuecomment-2482376705
This API is already supported and exposed by Prometheus API Router. I agree it is better to handle it in Query Frontend only but we should be able to enable it today on both Query Frontend and Querier by registering the route here.
