Description

Currently the Rust compiler assumes that all generated modules are rooted at the top-level of your crate (i.e. at lib.rs). There are many useful cases where you want to control exactly where the generated code lives (for example - you may want it to be inside another sub-module you control); typically this is done via thrift namespace definitions. The compiler currently ignores these declarations. It should be changed to:

1. recognize them if they exist, and generate code with the proper module paths
2. default to the current behavior if no namespace declarations exist
3. work properly in both cases with service inheritance.
