Update git submodules

* Update docs/submodules/storperf from branch 'master'
  - Creation of Local Docker for Daily Job

    Moves the dockerfiles for the different submodules/containers into
    their respective directories.
    Adds a docker compose file that can build the containers from the
    local filesystem, and mounts the local filesystem as a volume,
    making it easier for developer testing as local changes are
    automatically reflected in the final container.
