commit 406f521ef112fd7321d620a19d9ec305e773a513
Author: Johannes Grassler <johannes.grassler@suse.com>

Upstream status: merged into master, no stable/pike backport planned

Java persister config: defaults and robustness
    
    This commit adds defaults for configuration settings where
    that makes sense so they can be omitted. Likewise, unknown
    settings will now be ignored everywhere except for the
    database sections (the relevant configuration classes for that
    are in monasca-common).
