vmselect: limit end param max value by 2d in future (#2729)

* vmselect: limit `end` param max value by 2d in future

The change is applied only to service handlers like `/labels` or `/series`
and limits the `end` param by max value <= now() + 2 days. The same limit
is applied for the ingested data, so no reason to allow to request data
in future far than that.

The change is also needed for corner cases like https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2669
where too high `end` value triggers inefficient global index search.

* BUGFIX: [vmui](https://docs.victoriametrics.com/#vmui): properly apply the selected time range when auto-refresh is enabled. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2693).
* BUGFIX: [vmui](https://docs.victoriametrics.com/#vmui): properly update the url with vmui state when new query is entered. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2692).
* BUGFIX: [Graphite render API](https://docs.victoriametrics.com/#graphite-render-api-usage): properly calculate sample timestamps when `moving*()` functions such as [movingAverage()](https://graphite.readthedocs.io/en/stable/functions.html#graphite.render.functions.movingAverage) are applied over [summarize()](https://graphite.readthedocs.io/en/stable/functions.html#graphite.render.functions.summarize).
* BUGFIX: limit the `end` query arg value to `+2 days` in the future at `/api/v1/*` endpoints, because VictoriaMetrics doesn't allow storing samples with timestamps bigger than +2 days in the future. This should help resolving [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2669).
