Redo the way versioning works in freeIPA.
    
    The file VERSION is now the sole-source of versioning.
    
    The generated .spec files will been removed in the maintainer-clean targets
    and have been removed from the repository.
    
    By default a GIT build is done. To do a non-GIT build do:
    
     $ make TARGET IPA_VERSION_IS_GIT_SNAPSHOT=no
    
    When updating the version you can run this to regenerate the version:
    
     $ make version-update
    
    The version can be determined in Python by using ipaserver.version.VERSION
