(cherry picked from commit 05a64a8c14)
### Describe Your Changes
- Use common compose.yaml file for all victorialogs setups to set
version in a single place and override it on demand for each agent and
protocol
- Replaced multiple victorialogs instances in HA setup with single setup
with `deploy.replica` parameter set
- Added fluentd setup

* Many collectors don't support forwarding url query params to the remote system. It makes impossible to define stream fields for it. Workaround with proxy between VictoriaLogs and log shipper is too complicated solution.
* This commit adds the following changes:
* Adds fallback to to headers params, if query param is empty for:
_msg_field -> VL-Msg-Field
_stream_fields -> VL-Stream-Fields
_ignore_fields -> VL-Ignore-Fields
_time_field -> VL-Time-Field
* removes deprecations from victorialogs compose files, added more
output format examples for logstash, telegraf, fluent-bit
related issue: https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5310
* deployment/docker: add VictoriaLogs configuration
Signed-off-by: Zakhar Bessarab <z.bessarab@victoriametrics.com>
* deployment/docker/victorialogs: remove outdated comment
It was added in order to indicate that it is required to build VictoriaLogs manually before starting it at the time there was no public release available.
Currently, there is a public tag and it is not required to build it from sources.

- Parse protobuf if Content-Type isn't set to `application/json` - this behavior is documented at https://grafana.com/docs/loki/latest/api/#push-log-entries-to-loki
- Properly handle gzip'ped JSON requests. The `gzip` header must be read from `Content-Encoding` instead of `Content-Type` header
- Properly flush all the parsed logs with the explicit call to vlstorage.MustAddRows() at the end of query handler
- Check JSON field types more strictly.
- Allow parsing Loki timestamp as floating-point number. Such a timestamp can be generated by some clients,
which store timestamps in float64 instead of int64.
- Optimize parsing of Loki labels in Prometheus text exposition format.
- Simplify tests.
- Remove lib/slicesutil, since there are no more users for it.
- Update docs with missing info and fix various typos. For example, it should be enough to have `instance` and `job` labels
as stream fields in most Loki setups.
- Allow empty of missing timestamps in the ingested logs.
The current timestamp at VictoriaLogs side is then used for the ingested logs.
This simplifies debugging and testing of the provided HTTP-based data ingestion APIs.
The remaining MAJOR issue, which needs to be addressed: victoria-logs binary size increased from 13MB to 22MB
after adding support for Loki data ingestion protocol at https://github.com/VictoriaMetrics/VictoriaMetrics/pull/4482 .
This is because of shitty protobuf dependencies. They must be replaced with another protobuf implementation
similar to the one used at lib/prompb or lib/prompbmarshal .
* app/vlinsert: add support of loki push protocol
- implemented loki push protocol for both Protobuf and JSON formats
- added examples in documentation
- added example docker-compose
