The following actions are taken:
- Increase the TLS hashdshake timeout from 5 seconds to 10 seconds
- Increase dial timeout from 5 seconds to 30 seconds
- Specify DialContext instead of Dial in http.Transport. This allows properly handling
the Context arg during dialing the remote storage

* vmagent: add error log for skipped data block when rejected by receiving side
Previously, rejected data blocks were silently dropped - only metrics were update.
From operational perspective, having an additional logging for such cases is preferable.

* vmagent: throttle log messages about skipped blocks
The new type of logger was added to logger pacakge.
This new type supposed to control number of logged messages
by time.

* lib/logger: make LogThrottler public, so its methods can be inspected by external packages

This should improve the maximum data ingestion speed for highly-loaded vmagent instances
which run on beefy servers with many CPU cores and big amounts of RAM
The number of series per target can be limited with the following options:
* Global limit with `-promscrape.maxSeriesPerTarget` command-line option.
* Per-target limit with `max_series: N` option in `scrape_config` section.
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1561
This metric can be used for determining high saturation of every connection to remote storage with
an alerting query `rate(vmagent_remotewrite_send_duration_seconds_total) > 0.9s`.
This query triggers when a connection is satureated by more than 90%

* Change default value of '-remoteWrite.queues' to cgroup.AvailableCPUS() * 2 to reduce scrape interval
Default value of vmagent option '-remotewrite.queues' is 4 and default
size of vmagent ScheudleUnmarshalWorkers is number of CPUs, when available
CPUs is much greater than 4, e.g 32, worker are competing push queues
which will increase scrape interval and may cause scrape timeout.
* Update README and flag description

* new feature: relabel logging
Use scrape_configs[x].relabel_debug = true to log metric names inkl.
labels before and after relabeling. After relabeling related metrics
get dropped, i.e. not submitted to servers.
* vminsert wants relabel logging, too.
These numbers are exposed via the following metrics:
- vmagent_hourly_series_limit_current_series
- vmagent_daily_series_limit_current_series
Expose also the limits via the following metrics:
- vmagent_hourly_series_limit_max_series
- vmagent_daily_series_limit_max_series
This should increase block sizes and subsequently increase the maximum possible bandwidth per each connection to remote storage.
This, in turn, should reduce the probability of storing the data in local buffers.
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1235
This option can be useful when samples for the same time series are ingested with distinct order of labels.
For example, metric{k1="v1",k2="v2"} and metric{k2="v2",k1="v1"}.
* adds blocks drop at 400 BadRequest status code
recieved from remote storage,
not expected that remote storage will be able to handle it on retry
* removes error logging for dropped blocks,
its expected error
