  - Merge "first draft of 3 installers for Auto"
  - first draft of 3 installers for Auto

    JIRA: AUTO-42
    JIRA: AUTO-43
    JIRA: AUTO-46
    JIRA: AUTO-50

    a) Moved 3 scripts (Fuel/MCP, Compass4nfv, Apex/TripleO) from
    Auto Wiki pages to Auto repository. Did some cross-script alignment.
    Host folder in repository is: auto/ci. Abandoned JOID script:
    JOID seems to be unsupported after Fraser.

    b) Further fixes to these scripts can now be done in the Auto
    repository (not in Wiki), and inclusion in Auto CI jobs can also be
    tested.

    c) File names might be revisited, to account for variants: CPU, OS,
    scenario (openstack/kubernetes, HA/NOHA), size configs (vCPUs, RAM),
    etc. Or explore having these parameters as script parameters, maybe
    collapsing all scripts into one, where the installer would also be a
    script parameter.

    d) This batch of scripts is for x86 architectures; future
    versions/additions will cover Arm architectures;

    e1) Fuel/MCP script works (Fuel@x86)

    e2) Compass script works (x86, virtual deploy, NOHA)

    e3) Apex works on 2nd attempt; first attempt still has issues on
    blank servers (due to undocumented initial setup steps, causing
    errors which don't happen on servers where several tools and
    packages have already been installed).
    raised ticket on Apex: https://jira.opnfv.org/browse/APEX-633

    f) scripts all pass the shellcheck tool
