[MNG-6677] Ability to declare machine-readable license identifier for project

**[Vladimir Sitnikov](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=vladimirsitnikov)** opened **[MNG-6677](https://issues.apache.org/jira/browse/MNG-6677?redirect=false)** and commented

Current model for license is something, yet it is not machine-friendly.
Developers tend to put random data into `......`, and it is hard to analyze in automatic way.

What if we could use SPDX license identifiers/expressions for license information?

Note: currently POM allows to list multiple \ tags, and it is not clear how they should be treated (and? or?). So a machine-readable field should probably allow for AND/OR license expressions.

So it would be nice if there was a way to declare a machine-readable license tag.

I'm not affiliated with SPDX, however OSGi use those ids: https://osgi.org/specification/osgi.core/7.0.0/framework.module.html#framework.module-bundle-license
