* lib/protoparser: adds opentelemetry parser app/{vmagent,vminsert}: adds opentelemetry ingestion path Adds ability to ingest data with opentelemetry protocol protobuf and json encoding is supported data converted into prometheus protobuf timeseries each data type has own converter and it may produce multiple timeseries from single datapoint (for summary and histogram). only cumulative aggregationFamily is supported for sum(prometheus counter) and histogram. Apply suggestions from code review Co-authored-by: Roman Khavronenko <roman@victoriametrics.com> updates deps fixes tests wip wip wip wip lib/protoparser/opentelemetry: moves to vtprotobuf generator go mod vendor lib/protoparse/opentelemetry: reduce memory allocations * wip - Remove support for JSON parsing, since it is too fragile and is rarely used in practice. The most clients send OpenTelemetry metrics in protobuf. The JSON parser can be added in the future if needed. - Remove unused code from lib/protoparser/opentelemetry/pb and lib/protoparser/opentelemetry/proto - Do not re-use protobuf message between ParseStream() calls, since there is high chance of high fragmentation of the re-used message because of too complex nested structure of the message. * wip * wip * wip --------- Co-authored-by: Aliaksandr Valialkin <valyala@victoriametrics.com>
