* Remove obsolete query testing files
* Patch Fluent Bit log format to match netdata's format
* Update README with instructions on how to monitor Podman events logs

logsmanagement_function_execute_cb() is replaced by
logsmanagement_function_facets() which adds facets support to logs
management queries.
Internal query results header now includes additional fields
(log_source, log_type, basename, filename, chartname), that are used as facets.
Queries now support timeout as a query parameter.
A web log timestamp bug is fixed (by using timegm() instead of mktime().
web_api_v1 logsmanagement API is only available in debugging now.
