Provide a short article on how to use Wireshark to look 'into' the binary protocol that is gRPC.

[hutchig]

gRPC is a binary protocol and not self describing - so it can be hard to tell what traffic is flowing into
and out of a gRPC server.

It is possible to set up Wireshark to use gRPC .proto files to look 'into' the protocol's traffic:
https://www.wireshark.org/docs/wsug_html_chunked/ChProtobufSearchPaths.html

I thought it would be a useful skill to learn (for myself) how to use Wireshark in this way
and to document how it can be done.

I was unsure of this would be better as a short blog type article or as a page in the OpenLiberty
wiki pages (it is pretty geeky and only relevant to those using OL for gRPC but should be fairly
evergreen).

Very happy to do it either way and wanted an opinion?

See the below for some evidence of the applicability of wireshark:
