Previously vmgateway returned error for the requests with multitenant
tenant.
This commit allows to rate limit multitenant requests and apply global
rate limit for it.
Currently it supports only queries for rate limiting.
Related issue: https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7201
This commit also addresses gateway start-up crash if datasource.url is not accessible.
Previously vmgateway could crash at start-up with enabled rate limiting if datasource for metrics
was not avaiable for any reason. It seems, that crash is expected. But in fact it's not. For instance, datasource could be in restart phase.
Replaces crash with log message error. It increased availability of vmgateway component.

This commit adds `metric_relabel_configs` and `relabel_configs` fields
into the `global` section of scrape configuration file.
New fields are used as global relabeling rules for the scrape targets.
These relabel configs are prepended to the target relabel configs.
This feature is useful to:
* apply global rules to __meta labels from service discovery targets.
* drop noisy labels during scrapping.
* mutate labels without affecting metrics ingested via any of push
protocols.

In this case the _msg field is set to the value specified in the -defaultMsgValue command-line flag.
This should simplify first-time migration to VictoriaLogs from other systems.
- Remove leading whitespace from the first lines in 'HTTP parameters' chapter.
This whitespace isn't needed for the markdown formatting.
- Add leading whitespace for the second sentence in the list bullet describing AccountID and ProjectID HTTP headers.
This fixes markdown formatting for this list bullet.
This msy be useful when ingesting logs from different sources, which store the log message in different fields.
For example, `_msg_field=message,event.data,some_field` will get log message from the first non-empty field:
`message`, `event.data` and `some_field`.
If the number of output (bloom, values) shards is zero, then this may lead to panic
as shown at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7391 .
This panic may happen when parts with only constant fields with distinct values are merged into
output part with non-constant fields, which should be written to (bloom, values) shards.

This allows reducing the amounts of data, which must be read during queries over logs with big number of fields (aka "wide events").
This, in turn, improves query performance when the data, which needs to be scanned during the query, doesn't fit OS page cache.
This improves performance of `field_values` pipe when it is applied to large number of data blocks.
This also improves performance of /select/logsql/field_values HTTP API.

It is possible for in-memory part to be empty if ingested samples are
removed by retention filters. In this case, data will not be discarded
due to retention before creating in memory part. After in-memory parts
merge samples will be removed resulting in creating completely empty
part at destination.
This commit checks for resulting part and skips it, if it's empty.

- add a separate index cache for searches which might read through large
amounts of random entries. Primary use-case for this is retention and
downsampling filters, when applying filters background merge needs to
fetch large amount of random entries which pollutes an index cache.
Using different caches allows to reduce effect on memory usage and cache
efficiency of the main cache while still having high cache hit rate. A
separate cache size is 5% of allowed memory.
- reduce size of indexdb/dataBlocks cache in order to free memory for
new sparse cache. Reduced size by 5% and moved this to a separate cache.
- add a separate metricName search which does not cache metric names -
this is needed in order to allow disabling metric name caching when
applying downsampling/retention filters. Applying filters during
background merge accesses random entries, this fills up cache and does
not provide an actual improvement due to random access nature.

Auto-adjust `-remoteWrite.concurrency` cmd-line flags with the number of
