Using Docker volumes for persistent data in the bifrost container is
necessary for upgrading the bifrost services.

This change adds the following volumes:

* bifrost_httpboot
* bifrost_ironic
* bifrost_mariadb
* bifrost_rabbitmq
* bifrost_tftpboot

Ironic creates hardlinks between the TFTP master image store and the
HTTP root path when iPXE is enabled. With different Docker volumes
used for these locations we run into
https://bugs.launchpad.net/ironic/+bug/1507894 during deployment. If
we use a directory under /httpboot to store the master images this
issue is avoided.

Using a kolla_logs volume ensures that logs are persistent beyond the
lifespan of the bifrost_deploy container. This is necessary to support
upgrading the bifrost services. It also opens the possibility of log
forwarding, although we do not currently deploy a fluentd container on
the bifrost host.

Bifrost now targets the play in the install.yml playbook at the
target Ansible group instead of localhost.

This change uses the target inventory file to pick up this group
and avoid a 'noop' playbook.

bifrost container.

The bootstrap.yml playbook attempts to source
/opt/stack/ansible/hacking/env-setup and fails because no such file
exists (ansible is not installed in the location /opt/stack/). This step
is not required since the command bash ./scripts/env-setup.sh does not
install ansible from source in the Bifrost container as ansible is
already installed in the base image used by the Bifrost container.
