* Update docs/submodules/infrautils from branch 'master'
  to 05e6dec061dce1899678beced0f649d17313df08
  - Enable findbugs-slf4j

    porting I60b127526ccc057d37ef900b7502f4ea84517d8a
    https://git.opendaylight.org/gerrit/#/c/66449/
    from odlparent to infrautils.

    see also https://lists.opendaylight.org/pipermail/odlparent-dev/2018-March/001774.html
    for more background about why we're not just waiting for odlparent anymore.

    in I91f21504c9a18580733a1eedd3ba379de79d37c2
    https://git.opendaylight.org/gerrit/#/c/69140/ there is something very
    similar done in project netvirt, with a slightly different
    implementation (using a SNAPSHOT odlparent, which this approach avoids).
