Update git submodules

* Update docs/submodules/releng/builder from branch 'master'
  to 82a320615a6f6db6c62edf9d3cf3188acfeb0354
  - Merge "Use infrautils.ready to check controller UP-ness"
  - Use infrautils.ready to check controller UP-ness

    infrautils.ready is only there in Oxygen and beyond so still
    need to leave the old logic for Carbon and Nitrogen CSIT to
    use. As those age out, we can remove the old logic. I think
    that will be in 12-18 months.
