Yash Tibrewal 5029af9578 OpenCensus: Use new CallTracer interfaces (#32618 ) This change mostly aims to get OpenCensus to use the new ServerCallTracer interface. Note that the interfaces nor the code are in their final states. There are a bunch of moving pieces, but I thought this might be a nice mid-step to check-in and make sure that our internal traces can also work with these changes. Overall changes - 1) call_tracer.h shows what the hierarchy of new call tracer interfaces looks like. Open to renaming suggestions. 2) Moved most of the common interface between `CallAttemptTracer` and `ServerCallTracer` into a common `CallTracerInterface`. We should be able to eventually move `RecordReceivedTrailingMetadata` and `RecordEnd` as well to these common interfaces, but it requires some additional work. 3) The compression filter is now responsible for recording the recv and send messages for both the subchannel call and the server, and adds in ability to record compressed and decompressed messages as well. 4) The OpenCensus server filter now uses the new `ServerCallTracer` interface, and so doesn't need to be a filter anymore. 5) A new ServerCallTracerFilter was added. Ideally, we should be able to move it to the current connected filter, but it is in a bit of an interesting state right now, so I would prefer making those changes in a separate PR with Craig's eyes on it. 6) A new context element `GRPC_CONTEXT_CALL_TRACER_ANNOTATION_INTERFACE` was created that replaces the old `GRPC_CONTEXT_CALL_TRACER`, and the new `GRPC_CONTEXT_CALL_TRACER` is mainly to pass the `CallAttemptTracer` down the stack. This should go away in the new promise-based world. <!-- If you know who should review your pull request, please assign it to that person, otherwise the pull request would get assigned randomly.
