Review comment:
Hard coding the address is not ideal since the outcome of the test is
now dependent on localhost:9000 being available. You can instead [poll for an
open port using net.Listen() like in the expansion service start-up
code](https://github.com/apache/beam/blob/2aa4da02bc49be72b45e8327c5233c0e4938e59d/sdks/go/pkg/beam/core/runtime/xlangx/expansionx/process.go#L37)
