Install location is not configurable

[Stephane Miller]

As part of the installation process, bifrost clones git repositories for ansible, ironic, diskimage-builder, and shade into /opt/stack. However, this path is not currently configurable. Users should be able to specify where these resources are located.

Part of the work to enable this has been done in https://review.openstack.org/#/c/324789/ but we need to extend this to include the playbooks.

i started working on closing the bug and have a semi-working patch. https://review.openstack.org/#/c/329191/1.

This patch seems to work when i am inside the VM and we call the install.yml playbook where the defaults/main.yml of the two playbook does a env lookup. This fails though during the bifrost vagrant VM provisioning step where the install.yml happens with 'become: yes' which seems to null almost all of the env variables and the lookup always returns null.

We can pass the value as 'ansible_install_root=XXXX' in the provision.yml file and that might work. Any recommendations on the best way to solve this would be much appreciated.

It appears that we made it such that ansible could be installed to another path, but not the bulk of the source or what bifrost places. tl;dr, there is still work to be done.
