Use Assume Yes Flag for Datastore Elements

[Auston McReynolds]

some datastore elements don't use "-qy" for dependencies:

    + set -o xtrace
    + export DEBIAN_FRONTEND=noninteractive
    + DEBIAN_FRONTEND=noninteractive
    + apt-get install curl
    Reading package lists... Done

    The following extra packages will be installed:

    The following packages will be upgraded:
      curl libcurl3
    2 upgraded, 0 newly installed, 0 to remove and 85 not upgraded.
    Need to get 296 kB of archives.
    After this operation, 0 B of additional disk space will be used.
    Do you want to continue? [Y/n] Y

which can cause diskimage-builder failures depending on your host/guest os's drift from the repo you're consulting.
