feat(maven): settings.xml registry extraction

[Chumper]

Changes:

Introduces registry url extraction for maven for settings.xml
When a settings.xml resides in the repository under .mvn/settings.xml, .m2/settings.xml or settings.xml then we try to parse the file and extract registry urls from the <mirrors> and <repositories> child elements.

This is then added to the registry urls Renovate uses to look up the maven packages.

Advantage: This frees the repository owner from adding all maven registries manually to the renovate.json.
Instead they can rely on Renovate extracting them from the settings.xml if available.

Todo:

• Documentation
• Live Repo test: https://github.com/renovate-support/maven-registry-extract

Context:

Closes #13448

Any suggestion on how to test the line?

The extractPackage method always sets the registryUrls so the else case can only be reached with extensive mocking as it seems to me.

Easy way out would be to annotate it.

Edit: I have added the annotation for now, let me know if you want this changed.
