[RFE] New deploy driver using ansible for node bootstraping

[Vladyslav Drok]

Current use mode of IPA consists of clearly defined steps (clean disk, configure raid, download image etc). It should be possible to define those steps as parametrized configuration units and use existing configuration managers to perform those steps on the BM node during bootstrap process.

Ansible is already mature enough configuration management tool. As it is written in Python, it seems like a nice fit to OpenStack and Ironic in particular. Moreover, its minimal requirement is presence of Python and SSH access on node to be configured, so almost any modern Linux image can be used as bootstrap image without a need of any specific agent inside.

It is proposed to create a new deploy driver that would use Ansible for node configuration. Each appropriate step of node provision then is defined as Ansible role.

I'm not sure if this makes sense for the project, however I'm interested in hearing more. Could you please write a spec for this?

Although the ansible driver is in ironic-staging-drivers, they still would like it in-tree at some point.

Spec is at https://review.openstack.org/#/c/241946/

    Add ansible deploy interface

    this patch pulls the ansible deploy interface code
    and related ansible playbooks and auxiliary files
    from ironic-staging-drivers project into main ironic tree.

    As discussed in the spec, the use of ramdisk callbacks
    (lookup and hearbeats) is now mandatory with this deploy interface.
    Playbooks and modules were updated to require Ansible>=2.4,
    and custom Ansible module for executing 'parted' was replaced
    with usage of built-in Ansible module.

    The custom Ansible callback plugin now uses journald logger
    by default to adapt to the default DevStack setup.

    Documentation and devstack plugin changes enabling automated
    testing of this interface will be proposed in followup patches.
