[dev] build alpine docker image failed when enable grpc

[Quentin Young]

In the future, please send patch files as attachments. They are difficult to
apply when pasted into an html email body.

I took a brief look at what you described and confirmed that it does fail to
build with your patch, although the error I get is different - something about
needing at least C++14.

Whether the patch is the correct way to build with GRPC on Alpine, I'm not
sure. I don't think anyone has ever done that, so you are in uncharted
territory.

If you figure it out please drop us a line on how you did it and we can write
it down in the docs, and potentially patch the image build to support it.
