This patch removes the git clone machinary and sets the Ansible installation to happen from pypi by default. The ANSIBLE_PACKAGE environment variable can still be used to change the install to use a git source if the deployer wishes to do so. This change is implemented to remove another moving part from the Ansible bootstrap process, allowing a pypi/wheel mirror to be used instead. Change-Id: I137956530a11b0b23adb41f6b38dd55cde892221
