Fix remote bootstrap from Windows control host

This commit addresses the failure due to encoding error which occurs
during the apply of puppet bootstrap manifest if the playbook is run
from a Windows control host.

In addition:
  - readme is updated to specify netaddr package dependency. This
    package is not included by default as part of Cygwin.
  - ansible related packages are removed from centos_iso_image.inc
    as they will be automatically pulled in per playbookconfig
    spec.
