Update git submodules

* Update infrautils from branch 'master'
  to 61f3a374264b8e6c6c0d8bce6b05431c77fa7a06
  - fix logging of (supposedly) "CRITICAL" condition
    
    if it's "CRITICAL", it most probably better be LOG.error() instead info,
    and it would REALLY help to have the cause included; see also
    KengoTODA/findbugs-slf4j#74.
    
    actually, perhaps this really should re-throw... let me propose that in
    a follow-up change, and we can discuss if there is any reason to only go
    half the way or merge both steps.
