lib/fs: replace fs.OpenReaderAt with fs.MustOpenReaderAt
...
All the callers for fs.OpenReaderAt expect that the file will be opened.
So it is better to log fatal error inside fs.MustOpenReaderAt instead of leaving this to the caller.

Revert "app/vmselect/promql: remove metric name after applying ceil
, floor
and round
functions in order to be more consistent with Prometheus"
...
This reverts commit ac45082216
.
Reason for revert: the previous behavior for VictoriaMetrics is easier to understand and use by users -
functions, which don't change the meaning of the time series shouldn't drop metric name.
Now the following functions do not drop metric names:
* ceil
* floor
* round
