When generating grpc for Nodejs, the documentation for grpc says to do the following:

grpc_tools_node_protoc --js_out=import_style=commonjs,binary:. --grpc_out=. --plugin=protoc-gen-grpc=`which grpc_tools_node_protoc_plugin` helloworld.proto

note the --plugin=<generator_name>=<binary_location_on_disk>

This is currently possible in Gunk by doing the following:

# .gunkconfig

[generate js]
import_type=commonjs
binary

[generate]
command=/path/to/protoc-gen-grpc

but it isn't possible to do this if doing a shortened generate section; should we make it possible? we could do similar to the following:

# .gunkconfig

[generate js]
import_type=commonjs
binary

[generate grpc]
plugin=/path/to/protoc-gen-grpc

I am not sure if this is something we want, but if we wanted to keep it similar to protoc cli then it is pretty trivial to add something like this in?
