It is not entirely clear to someone writing their
own templates how to distribute hiera keys to different
roles. Let's clear this up with a more extensive description.

We don't need all the steps currently enabled for either batched
or concurrent updates, so decrease them. In future we can perhaps
introspect the task tags during plan creation and set these
dynamically.

Some services (e.g ceph mon) require upgrading in batches (the old
upgrade architecture did the ceph mon upgrade one controller at a
time). This interface enables doing the same, and over time we
can probably move more services into this interface (e.g when
services support rolling upgrades) to reduce downtime.

This enables the deployer to dynamically add nova metadata to the
servers based on the output of service profiles that implement the
metadata_settings key in the role_data output for the profiles.
One can set an implementation via the OS::TripleO::ServerMetadataHook
resource, which currently is set as OS::Heat::None. So, because of
the default implementation, if left untouched it actually does
nothing.
Currently, besides the list, which is metadata_settings, this hook also
takes the name of the node that it's setting the metadata for.
This is useful for nova vendordata plugins that can parse said metadata.

This shows how we could wire in the upgrade steps using Ansible
as was previously proposed e.g in https://review.openstack.org/#/c/321416/
but it's more closely integrated with the new composable services
architecture.
It's also very similar to the approach taken by SpinalStack where
ansible snippets per-service were combined then run in a series of
steps using Ansible tags.
This patch just enables upgrade of keystone - we'll add support for
other patches in subsequent patches.

We removed Step 6 in Iae33149e4a03cd64c5831e689be8189ad0cf034b
but forgot to update the README. Similarly we made all roles
use the same steps in Ia2ea559e8eeb64763908f75705e3728ee90b5744
so the comment is no longer true.

The new global_config_settings output is meant to contain
additional hieradata distributed by the services to all role types.

Similar to the https://review.openstack.org/#/c/259568 which added support
for the composable services StepConfig and ServiceConfigSettings parameters
so that the Controller role supports composable services, this adds those
interfaces for the ObjectStorage role.
Note that at this time the ObjectStorage post config only supports steps
2, 3 and 4, not all those in services/README.rst

This patch wires in a new for Mitaka Heat feature
that allows us to dynamically include a set of nested
stacks representing individual services via a Heat resource chain.
Follow on patches will use this interface to decompose the controller
role into isolated services.
