[MNG-5932] Per-user and per-project logging configuration

**[Brian Oxley](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=binkley)** opened **[MNG-5932](https://issues.apache.org/jira/browse/MNG-5932?redirect=false)** and commented

It would be of much use to support per-user and per-project logging configuration. This supports cases where different projects have different maven logging requirements (e.g., post-processing maven output as part of a pipeline). Currently I need to change the maven installation to, for example, swap out logback for simplelogger, or to change the simplelogger settings.

As a workaround on simplelogger I can use .mvn/jvm.config to pass system properties for simplelogger, but this is non-obvious and does not help with changing SLF4J implementation.

I would like to be able to use something like .mvn/logging/\ akin to conf/logging under $M2_HOME and/or lib/ext.
