Aliaksandr Valialkin 2ac5f00d98 app/vmselect: propagate errors from vmstorage to response to the client if -search.denyPartialResponse command-line flag is set
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/891

This commit also adds `"isPartial":{true|false}` field to `/api/v1/*` responses. `"isPartial":true` is set when the response
is based on a partial data because some of vmstorage nodes weren't available during query processing.
