We're using a different provider (Lightstep), but we also would like to not run the OpenCensus collector as an intermediate. |

It'd be good if it's possible to get this back on the table:
What I'd also suggest is more flexibility on the span propagation as all OTEL implementations must support W3C TraceContext, Baggage and Jaeger in addition to the older B3 format. |

This is becoming more pressing now, due to some changes in the opentelemetry-collector which started to disable and drop support for the opencensus bridge in current/upcoming versions, see:
Without native OTLP support in linkerd-proxy, one is forced to use an outdated/aging version of the opentelemetry-collector going forward. |

This mirrors and duplicates most of the logic from the existing OpenCensus exporter to keep the functionality as similar as possible. Setting up the proxy to use this exporter will come in a follow-up. (#10111)[linkerd/linkerd2#10111] Signed-off-by: Scott Fleener <scott@buoyant.io>

This wires up the proxy to optionally use OpenTelmetry as the format for exported traces. Currently, this defaults to the existing OpenCensus exporter. Changing the default and eventually removing the OpenCensus exporter will come later. (#10111)[linkerd/linkerd2#10111] Signed-off-by: Scott Fleener <scott@buoyant.io>

In preparation for supporting the OpenTelemetry protocol for the proxy's traces, this vendors the relevant protobufs as well as some convenience helpers here. This works around the fact that the existing `opentelemetry` crates do not support the version of tonic that we currently use (0.10), and this vendoring can be removed once we update.

Allows setting the trace export protocol env var (`LINKERD2_PROXY_TRACE_PROTOCOL`) on instances of the proxy using the existing mechanisms we have today for setting the trace collector endpoint (helm values, annotations, etc.). Currently defaults the protocol to `opencensus` to match the behavior we have today. \linkerd#10111 Signed-off-by: Scott Fleener <scott@buoyant.io>

Observability tools and vendors are now starting to support the OTLP protocol directly (See: https://opentelemetry.io/vendors/) so I think this should remain open as it would be ideal not to have to run an intermediary collector that speaks the OpenCensus protocol.
For example we run Datadog in our environment and have configured our applications to send B3 traces there directly. We are propagating the B3 headers through our service mesh but introducing another component to manage is not desirable.
