Update git submodules

* Update docs/submodules/aai/aai-common.git from branch 'master'
  to 703072969c51068d6a7aadf7131a545eabab87cd
  - Merge "Update dmaap to use logging context"
  - Update dmaap to use logging context

    Change from using the MDC to use Logging Context
    When an update happens on a vertex,
    there is no need to update the aai-node-type
    as a vertex type will not be modified and
    this causes some issues with how janusgraph works
