Bootstrapping hgitaly development
We vendor the protobuffer definitions from the
gitaly-proto upstream repo, generate the stubs for
commit.proto and implement but one call.
This little experiment got me convinced that we'll spend some time being really sure of what's expected inside the various fields, and especially with corner cases.
Spelled it the other way round, getting started with gRPC and pytest-grpc wasn't so hard.
