enable biforst for baremetal deployment

Registered by sean mooney

Bifrost is a set of Ansible playbooks that automates the task of deploying a base image onto a set of known hardware using ironic.
see https://github.com/openstack/bifrost

this blueprint proposes an optional biforst container to enable baremetal provisioning of servers for use in a subsequent kolla deployment.

this support in not a replacement for current ironic support for the baremetal as a service usecase but optional
way to provision your servers for use with kolla.

the biforst contaienr will support both a bring your own iamge approch and building a base image to deploy on the host using
disk image builder.

while disk image builder can be used to create a custom image with all kolla dependcies pre installed this is currently not requried but could be added at a later date.

in paraell to this effort and intall_deps playbook should create to manage installation of build and or deploy dependencies on arbitray nodes. this install_deps playbook can be reused with existing baremetal deployment tools and will have no dependency on
bifrost to allow operators to reuse there existing infrastructure.

when all components are in place the workflow with bifrost will be as follows.

clone kolla
run install_deps playbook to prep localhost
build kolla images
deploy biforst container
enroll and deploy servers with biforsts
run intall_deps playbook on all servers
run kolla deploy on all servers.

the scope of this blueprint will cover the creation of the bifrost container and associated ansible playbook modification to deploy it. the install_deps playbook will be covered in a separate blueprint.
