Support for PartialSuccess responses #193
Description
The OTLP protocol supports a response that indicates partially-successful writes that cannot be interpreted as total failures or retried. An OTel-Arrow pipeline should support the same backwards-propagation of error state.
This implies adding to the Arrow status response with the PartialSuccess corresponding with the data.
Note however this support is not yet propagating backwards beyond the exporterhelper either, which is an open issue. open-telemetry/opentelemetry-collector#6686
