Subject: [PATCH] Update git submodules

* Update devstack from branch 'master'
  - Merge "Set ETCD_USE_RAMDISK=True by default"
  - Set ETCD_USE_RAMDISK=True by default

    Cinder and etcd are enabled by default and by default
    cinder uses etcd as a distributed lock manager with
    tooz as an intermediary. We see a lot of ToozConnectionErrors [1]
    in the cinder logs when etcd is backed up [2] which results in
    cinder operations timing out causing test failures, like
    when a volume is not deleted within a given time.

    This changes ETCD_USE_RAMDISK=True by default to try and
    alleviate some of the pressure. An alternative is if we know
    we're in a single-node job we could just not use a DLM for
    Cinder.

    [2] etcd[26824]: sync duration of 12.076762123s, expected less than 1s
