enhancement(ClickHouse sink): Adding date_time_best_effort flag

[DarkWanderer]

Added support for ClickHouse setting which will allow to ingest timestamp with subsecond precision (DateTime64 column). This trades off some performance cost on server side for ability to store same timestamp precision as vector uses

Closes #1672

Regression Test Results

Run ID: aee6097f-bb6e-4294-b862-f42433e295d8
Baseline: bfad266
Comparison: 652862b
Total vector CPUs: 7

Explanation

A regression test is an integrated performance test for vector in a repeatable rig, with varying configuration for vector. What follows is a statistical summary of a brief vector run for each configuration across SHAs given above. The goal of these tests are to determine, quickly, if vector performance is changed and to what degree by a pull request. Where appropriate units are scaled per-core.

The table below, if present, lists those experiments that have experienced a statistically significant change in their bytes_written_per_cpu_second performance between baseline and comparision SHAs, with 90.0% confidence OR have been detected as newly erratic. Negative values mean that baseline is faster, positive comparison. Results that do not exhibit more than a ±5% change in mean bytes_written_per_cpu_second are discarded. An experiment is erratic if its coefficient of variation is greater than 0.1. The abbreviated table will be omitted if no interesting changes are observed.

No interesting changes in bytes_written_per_cpu_second with confidence ≥ 90.00% and absolute Δ mean >= ±5%.

Fine details of change detection per experiment.
