Multistage: connect(..) failed: Address family not supported by protocol release v1.0.0

Pinot1.0.0 using multistage v2 option deployed from distribution, gets error running query.

Can see server/broker listening on the query and mailbox ports ok but client cannot connect to query.

Tried switching netty native v java implementation = no difference
Tried prefer ipv4 = no difference apart from the query showed that multistage was not enabled until the cluster config enable multistage was added in.

Online search suggests a shading issue with the grpc library in the distro.

Reproduce the failure with the Pinot 1.0.0 distribution, multistage v2, and the reported query, then start from QueryDispatcher.java:144 and the MultiStageBrokerRequestHandler.java:179 stack-trace entries. Inspect the packaged gRPC/Netty dependencies and compare them with the non-shaded implementation; done means multistage queries can connect to the query and mailbox ports without the address-family error.
