Toby Oxborrow c88534e169 Fix run-aio-build.sh for curl one-liner
The developer documentation to run an AIO build includes a curl
one-liner to run the scripts/run-aio-build.sh script. However, due to
the way it sources other scripts it will fail to execute.

This change sources those scripts in a way to allow them to be run from
curl piped to bash and also from a local git checkout.

* In run-aio-build.sh it has cd to a fresh checkout so the path can be
  assumed and hard-coded.
* In bootstrap-aio.sh and bootstrap-ansible.sh we now test the existing
  behaviour first (which will work if you executed these scripts
  directly from a git checkout) or from a scripts subdirectory of the
  currrent path (which will work if you ran the curl one-liner).

Example of documentation which includes the curl one-liner:
http://docs.openstack.org/developer/openstack-ansible/developer-docs/quickstart-aio.html#running-an-aio-build-in-one-step

The curl one-liner:
curl https://raw.githubusercontent.com/openstack/openstack-ansible/master/scripts/run-aio-build.sh | sudo bash
