Extract api to a separate module

We should think what should be versions-api.

For me versions-api should have only interfaces for component which can be extended / implemented as extension for versions-maven-plugin, like VersionComparator.

I would like to have a project structure like:

• versions-api - public api for external extending plugin
• versions-maven-plugin - core plugin
• versions-report-maven-plugin - dedicated plugin for Maven site reports
• versions-common/internal - shared implementation used in plugin, report-plugin - should be used only by versions project
