[MBUILDCACHE-125] Separate configuration/outputs per module

**[Gili](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=cowwoc)** opened **[MBUILDCACHE-125](https://issues.apache.org/jira/browse/MBUILDCACHE-125?redirect=false)** and commented

I'd like to provide a separate \ configuration per module in a multi-module project.

The only workaround that comes to mind is to add entries that capture the module name like this:

 
\../../database/target/classes\
 
This has me wondering if there are other settings that make sense to configure on a per-module basis instead of globally.

Start by reviewing the existing global configuration and how settings are applied across modules; the issue does not identify repository files, tests, or entry points. Define the per-module configuration scope and determine which other settings, if any, should follow the same model. Done means multi-module projects can configure outputs independently without the workaround described.
