Because of a side-effect import, we have the possibility of pulling in several unnecessary packages that are used by the plugin and not at runtime to implement protobuf structures. Setting these imports to `weak` prevents this from happening, reducing the total import set, reducing memory usage and binary size. Signed-off-by: Stephen J Day <stephen.day@docker.com>
