Add the support of storage and retrieval of samples with future
timestamps as requested in https://github.com/VictoriaMetrics/VictoriaMetrics/issues/827
What to expect:
- By default, the max future timestamp is still limited to `now+2d`. To
change it, set the `-futureRetention` flag in `vmstorage`. The max flag
value is currently limited to `100y`. It can be extended if we see a
demand for this, but it can't be more than `~ 290y` due to how the time
duration is implemented in Go. The flag value can't be less than `2d`.
- downsampling and retention filters (available in enterprise edition)
are currently not supported for future timestamps
- If `vmstorage` restarts with a smaller value of `-futureRetention`
flag, any future partitions that are outside the new future retention
will be automatically deleted.
- Data ingestion, data retrieval, backup/restore, timeseries (soft)
deletion, and other operations work with future timestamps the same way
as with the historical timestamps.
- In the cluster version, the affected binaries are `vmstorage` and
`vmselect`. This means that `vmselect` version must match `vmstorage`
version if you want to query future timestamps. `vminsert` was not
affected, so its version can be a lower one.
- If you downgrade the `vmstorage`, the data with future timestamps will
remain on disk and memory (per-partition caches) but won't be available
for querying.

Update `timeutil.ParseTimeAt` to check the time limits for all date/time formats, not just year.

Since funcs `ParseDuration` and `ParseTimeMsec` are used in vlogs,
vmalert, victoriametrics and other components, importing promutils only
for this reason makes them to export irrelevant
`vm_rows_invalid_total{type="prometheus"}` metric.
This change removes `vm_rows_invalid_total{type="prometheus"}` metric
from /metrics page for these components.

Use local timezone of the host server in this case. The timezone can be overridden
with TZ environment variable if needed.
While at it, allow using whitespace instead of T as a delimiter between data and time
in the ingested _time field. For example, '2024-09-20 10:20:30' is now accepted
during data ingestion. This is valid ISO8601 format, which is used by some log shippers,
so it should be supported. This format is also known as SQL datetime format.
Also assume local time zone when time without timezone information is passed to querying APIs.
Previously such a time was parsed in UTC timezone. Add `Z` to the end of the time string
if the old behaviour is preferred.

This should smooth CPU and RAM usage spikes related to these periodic tasks,
by reducing the probability that multiple concurrent periodic tasks are performed at the same time.
