Error in netty code when running from PyXenon (with mutual TLS)

[jhidding]

Just starting the server in mutual TLS mode gives me this error.

A version conflict.

• grpc-netty depends on netty 4.1.17
• hadoop-hdfs depends on netty 3.7.0 and io.netty:netty-all:4.0.23.Final

I will exclude the hadoop-hdfs deps
