Update git submodules

* Update docs/submodules/policy/distribution.git from branch 'master'
  to 48a745734533d42e2d9e7b9d04d08cbe8ee1b62c
  - Fix docker build in policy/distribution

    policyLoger.properties file was removed as part of moving to slf4j
    for logging. But the assembly.xml file was still refering to it. Since
    the file was not there the /bin directory was missing from the
    created package. Resulting in docker builds failing.
