The buffer can be quite big under high ingestion rate (e.g. more than 100MB).
This leads to increased memory usage between buffer flushes.
So it is better to re-create the buffer on every flush in order to reduce memory usage
between buffer flushes.
This should improve maintainability of the code related to rollup functions,
since it is located in rollup.go
While at it, properly return empty results from holt_winters(), rate_over_sum(),
sum2_over_time(), geomean_over_time() and distinct_over_time() when there are no real samples
on the selected lookbehind window. Previously the previous sample value was mistakenly
returned from these functions.

Currently the docker-compose examples for loading `victoriametrics-datasource` uses 2 environment variables:
- `GF_ALLOW_LOADING_UNSIGNED_PLUGINS`
- `GF_DEFAULT_APP_MODE`
I believe both of the env vars are trying to achieve the same thing. `GF_DEFAULT_APP_MODE` disables code signing for all plugins and `GF_ALLOW_LOADING_UNSIGNED_PLUGINS` intends to disable code signing for just `victoriametrics-datasource`.
Keeping the scope narrowed to just `victoriametrics-datasource` would be preferable in this case.
Unfortunately `GF_ALLOW_LOADING_UNSIGNED_PLUGINS` is misspelled. According to [grafana docs](https://grafana.com/docs/grafana/latest/setup-grafana/configure-grafana/#override-configuration-with-environment-variables), the format is supposed to be `GF_<SectionName>_<KeyName>`. In other words the current env var is missing the section name.
This PR proposes to:
1. fix the typo
2. remove the global disablement of code signing
Alternatively, if you prefer to keep codesigning disabled globally, please remove `GF_ALLOW_LOADING_UNSIGNED_PLUGINS` env var as it confuses things

- Consistently return the first `limit` log entries if the total size of found log entries doesn't exceed 1Mb.
See app/vlselect/logsql/sort_writer.go . Previously random log entries could be returned with each request.
- Document the change at docs/VictoriaLogs/CHANGELOG.md
- Document the `limit` query arg at docs/VictoriaLogs/querying/README.md
- Make the change less intrusive.
