app/vmselect: return 503 status code when partial responses are denied and some of vmstorage nodes are temporarily unavailable
This should help detecting this case and automatic retrying the query at healthy cluster replica
in another availability zone.

This commit is needed as a preparation for automatic query retry at another backend at vmauth on 5xx errors
as described at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4792#issuecomment-1674338561

vmselect performs the following tasks:

  • Splits incoming selects to tasks for vmstorage nodes and issues these tasks to all the vmstorage nodes in the cluster.

  • Merges responses from all the vmstorage nodes and returns a single response.

The vmui directory contains static contents built from app/vmui package with make vmui-update command. The vmui page is available at http://<vmselect>:8481/select/<accountID>/vmui/.
