CHANGES:

• plugin: Plugins written in other languages can optionally start to advertise whether they support gRPC broker multiplexing. If the environment variable PLUGIN_MULTIPLEX_GRPC is set, it is safe to include a seventh field containing a boolean value in the |-separated protocol negotiation line.

ENHANCEMENTS:

• Support muxing gRPC broker connections over a single listener [GH-288]
• client: Configurable buffer size for reading plugin log lines [GH-265]
• Use buf for proto generation [GH-286]

• deps: bump golang.org/x/text to v0.13.0 [GH-285]
