logsql: add a flag to limit the maximum query time range

[func25]

Is your feature request related to a problem? Please describe

Large time-range queries can scan enormous amounts of logs and consume a disproportionate amount of CPU, memory, and I/O especially in production environments with multiple concurrent users.

Describe the solution you'd like

Introduce a time-range limit flag to protect clusters from resource-heavy queries.

Also addresses: #50

The -search.maxQueryTimeRange command-line flag has been added into VictoriaLogs in the commit 656185c . See these docs.

This commit will be included in the next release. In the mean time it is possible to build VictoriaLogs from this commit according to these instructions and verifying whether the added command-line flag works as expected.

VictoriaLogs v1.31.0 supports the -search.maxQueryTimeRange command-line flag as described above. Closing the feature request as done.
