Update git submodules

* Update docs/submodules/releng from branch 'master'
  - Merge "slave-params: Add fuel/armband bridge information"
  - slave-params: Add fuel/armband bridge information

    This information was previously fetched from securedlab, via a
    POD-specific "local_env" file which was sourced at deploy time.

    Since this information can't be parametrized via PDF, nor is it
    sensitive enough to hide in securedlab, move it to releng.
