Description
### Use Case
Telegraf open telemetry plugin assumes gRPC input.
However there are applications (example: pulp) that log open telemetry using http protobuf port 4318)
Changing the service address to use port to 4318 in the current collector does not change its behavior of expecting gRPC data.
Please add support for http protobuf (already present on the http input plugin) to the otel input
### Expected behavior
When listening on service address with port 4318
the otel input should accept and parse http protobuf POST data
### Actual behavior
When listening on service address with port 4318
the otel input still expects gRPC input data
