Thanks to Joshua Ryder for pointing to this.

app/vmselect: adjust end arg instead of adjusting start arg if start > end
...
`start` arg has higher chances to be set properly comparing to `end` arg,
so it is expected that the `end` arg could be adjusted if it was set incorrectly.

app/vmselect/prometheus: add -search.maxLookback command-line flag for overriding dynamic calculations for max lookback interval
...
This flag is similar to `-search.lookback-delta` if set. The max lookback interval is determined dynamically
from interval between datapoints for each input time series if the flag isn't set.
The interval can be overriden on per-query basis by passing `max_lookback=<duration>` query arg to `/api/v1/query` and `/api/v1/query_range`.

- Do not overwrite last points by the previous NaNs, since this may result in empty time series.
