This commit changes journald ingestion validation regex:
from `^[A-Z_][A-Z0-9_]+` to `^[A-Z_][A-Z0-9_]*`.
It's needed to properly support entities with single-character
names.

Adding Accept-Encoding response header to support content negotiation,
which was introduced in [this
PR](https://github.com/systemd/systemd/pull/34822) and enables
compression on journald
(cherry picked from commit 3c9f9f49b0)
Previously vl_rows_ingested_total metric was tracked individually per each supported data ingestion protocols.
It is better from maintainability PoV tracking this metric consistently in a single place - at logMessageProcessor.AddRow() function
in the same way as vl_bytes_ingested_total metric is tracked.
This is a follow-up for 50bfa689c9
This metric tracks an approximate amounts of bytes processed when parsing the ingested logs.
The metric is exposed individually per every supported data ingestion protocol. The protocol name
is exposed via "type" label in order to be consistent with vl_rows_ingested_total metric.
Thanks to @tenmozes for the initial idea and implementation at https://github.com/VictoriaMetrics/VictoriaMetrics/pull/7682
While at it, remove the unneeded "format" label from vl_rows_ingested_total metric.
The "type" label must be enough for encoding the data ingestion format.
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`.
