Including configuration/settings.xml in FIS Maven archetypes

The FIS s2i templates point to quickstart project repos which contain a configuration/settings.xml that is used during s2i source builds on OpenShift to include required MRRC repos. The same file is not included in FIS Maven archetypes. This means that Maven archetypes are broken for s2i source workflow OOTB unless the user configures additional template parameters to include additional Maven repos.

Suggest we add configuration/settings.xml to FIS Maven archetypes. Even if a user is doing s2i binary builds, the file is still useful as it shows the user what repos they need to add to $MAVEN_HOME/settings.xml.
