This should prevent from emitting too long lines when too long args are passed to logger.* functions.
For example, too long MetricsQL queries or too long data samples.
Adds `eval_offset` attribute for Groups.
If specified, Group will be evaluated at the exact time offset on the range of [0...evaluationInterval].
The setting might be useful for cron-like rules which must be evaluated at specific moments of time.

(cherry picked from commit 45c0e4bb31)
* Introduce flagutil.Duration
To avoid conversion bugs
* Fix tests
* Clarify documentation re. month=31 days
* Add fasttime.UnixTime() to obtain time.Time
The goal is to refactor out the last usage of `.Msecs`.
* Use fasttime for time.Now()
* wip
- Remove fasttime.UnixTime(), since it doesn't improve code readability and maintainability
- Run `make docs-sync` for syncing changes from README.md to docs/ folder
- Make lib/flagutil.Duration.Msec private
- Rename msecsPerMonth const to msecsPer31Days in order to be consistent with retention31Days

- Document the change at docs/CHANGELOG.md
- Set the default value for -vmstorageUserTimeout to 3 seconds. This is much better
than the 0 value, which means that TCP connection to unreachable vmstorage could block
for up to 16 minutes.
- Document -vmstorageUserTimeout at docs/Cluster-VictoriaMetrics.md
Initially, stream parse mode was reading data from response and parsing it on flight. This was causing longer delay to read the whole response and required increasing timeout value to allow data processing while reading. So that 908e35affd increased timeout value to fix this.
But after 74c00a8762 response in stream parse mode is saved into memory and then parsed eliminating necessity of having timeout value higher that for usual scrape.

* vmagent: retry failed write request on the closed connection
Retry failed write request on the closed connection immediately,
without waiting for backoff. This should improve data delivery speed
and reduce amount of error logs emitted by vmagent when using idle connections.

But if request object was already partially processed (body was read),
then retry will be unsuccessful.

It allows to modify exist series values.
User must write modified series into vminsert API
/insert/0/prometheus/api/v1/update/series
vminsert will generate id and add it to the series as __generation_id
label.
Modified series merged at vmselect side.
Only last series modify request at given time range will be applied.
Modification request could be exported with the following API request:
`curl localhost:8481/select/0/prometheus/api/v1/export -g -d
'reduce_mem_usage=true' -d 'match[]={__generation_id!=""}'`
