vlinsert: added opentelemetry logs support
Commit adds the following changes:

* Adds support of OpenTelemetry logs for Victoria Logs with protobuf encoded messages

*  json encoding is not supported for the following reasons:
   - It brings a lot of fragile code, which works inefficiently.
   - json encoding is impossible to use with language SDK.

* splits metrics and logs structures at lib/protoparser/opentelemetry/pb package.

* adds docs with examples for opentelemetry logs.

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

lib/protoparse/opentelemetry: reduce memory allocations

- 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.
