lib/protoparser: adds opentelemetry parser (#2570)
* 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.

- 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.
