Kevin Leimkuhler a3a240e0ef Add TapEvent headers and trailers to the tap protobuf (#3410) ... ### Motivation In order to expose arbitrary headers through tap, headers and trailers should be read from the linkerd2-proxy-api `TapEvent`s and set in the public `TapEvent`s. This change should have no user facing changes as it just prepares the events for JSON output in linkerd/linkerd2#3390 ### Solution The public API has been updated with a headers field for `TapEvent_Http_RequestInit_` and `TapEvent_Http_ResponseInit_`, and trailers field for `TapEvent_Http_ResponseEnd_`. These values are set by reading the corresponding fields off of the proxy's tap events. The proto changes are equivalent to the proto changes proposed in linkerd/linkerd2-proxy-api#33 Closes #3262 Signed-off-by: Kevin Leimkuhler <kleimkuhler@icloud.com>		2019-09-29 09:54:37 -07:00
