Description

Right now modules have no great way to register their relevant coders. One option is to use `AutoService`. We should explore this and other ways, so that coders can be adjacent to the library for which they are relevant.

Imported from Jira [BEAM-1436](https://issues.apache.org/jira/browse/BEAM-1436). Original Jira may contain additional context.
