Description
This MR adds a websocket to bgd browser-backend
which serves as a proxy for stream-based ByteStream reads. This is intended for use implementing LogStream functionality in bgd-browser without requiring grpc-web.
This MR also adds support for multiple BuildGrid instances to bgd browser-backend
. Previously, all services were assumed to be served by a single endpoint. This allows use of bgd browser-backend
with deployment topologies where the ByteStream, Operations, and ActionCache services are served in separate locations.
