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.
