Allow top level playbook files to import other playbook files, added some basic
playbook structure checking.
Soft import of paramiko since we have the SSH and local connection types now.  Packaging will still
require it.
Make adding tags to a playbook work as shorthand to tagging all tasks in the play.
Bring the cobbler external inventory script up to date with current usage (--list, --host hostname)

    Allow groups to be defined on a per-host basis

    This makes it possible to define on a per-host basis what groups a host is in.
    When managing a large set of systems it makes it easier to ensure each of the
    systems is defined in a set of groups (e.g. production/qa/development,
    linux/solaris/aix) rather than having to add systems to multiple disconnected
    groups.

    ----
      - host: system01

      - host: system02

      - host: system03

      - group: linux
        hosts:
        - system01
        - system02

      - group: solaris
        hosts:
        - system03

      - group: production
        hosts:
        - system01
        - system03

      - group: qa
        - system02

      - group: dbserver
        hosts:
        - system01

      - group: ntpserver
        hosts:
        - system02

      - group: webserver
        - system03
    ----

    Can be redefined as:

    ----
      - host: system01
        groups: [ linux, production, dbserver ]

      - host: system02
        groups: [ linux, qa, ntpserver ]

      - host: system03
        groups: [ solaris, production, webserver ]

Changelog update
Setup module no longer saves to disk, as templates are mostly useful in playbooks and this allows lots of simplifications
around file pathing and removes occasional permissions conflicts depending on how things are used.
Much streamlining around setup steps in playbooks, now only run setup once per play.
Warn if something loaded by vars_files is not a dictionary
Make the logic behind vars_files smarter, so host specific vars go into the setup cache, but other variables
are usable top level.  This allows vars_files data to be used, most of the time, just fine in with_items,
(error handling pending) but is mostly a memory and efficiency thing.
Error handling and magic around with_items, to let you know when variables are usable inside it and when not.
