lib/storage: increase rotation time for daily metricID cache

Browse Source 
This is follow-up for c5713a09d3

Originally, dateMetricID cache was fully rotate every 20 minutes. It
made daily-index pre-creation less efficient and caused CPU usage spikes
for index records lookup at midnight.

storage pre-fills index records for the next day in 1 hour before night.
But this rotation made only last 20 minutes before midnight visible in
the cache.

 This commit changes rotation period from 20 minutes to 2 hours ( 1 hour
 tick interval). While
it could slighlty increase cache memory usage ( in practice it shouldn't
be noticeable). It prevents from CPU usage spikes.

* FEATURE: [vmsingle](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/) and `vmselect` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/): calculate the lookbehind window as the median of the intervals between the last 20 raw samples within the requested time range for range queries. Previously, this calculation was based on the first 20 samples, using the last 20 samples should improve accuracy for recent data. See [#10281](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/10281).
* BUGFIX: [vmagent](https://docs.victoriametrics.com/victoriametrics/vmagent/): fix configuration reloading for `-remoteWrite.relabelConfig` and `-remoteWrite.urlRelabelConfig` when vmagent is launched with empty files. Previously, if vmagent started with an empty config, subsequent config reloads were ignored. See [#10211](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10211).
* BUGFIX: [vmsingle](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/) and `vmstorage` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/): prevent slow ingestion requests and CPU usage spikes during midnight daily-index creation. See [#10064](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10064).
* BUGFIX: [vmsingle](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/): fix a missing path error for `http://<victoriametrics-addr>:8428/zabbixconnector/api/v1/history`. See [10214](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/10214).
* BUGFIX: `vmstorage` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/): reduce default value for `storage.vminsertConnsShutdownDuration` flag from `25s` to `10s` seconds. It reduces probability of ungraceful storage shutdown at Kubernetes based environments, which has 30 seconds default graceful termination period value. See [#10273](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/10273)
* BUGFIX: [vmui](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#vmui): remove legacy `tenantID` query param and use the URL path as the single source of truth for multitenancy. See [#10232](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/10232).
