Services that access database have to read an extra MySQL configuration file
/etc/my.cnf.d/tripleo.cnf which holds client-only settings, like client bind
address and SSL configuration. The configuration file is thus used by
containerized services, but also by non-containerized services that still
run on the host.
In order to generate that client configuration file appropriately both on the
host and for containers, 1) the MySQLClient service must be included by the
role; 2) every containerized service which uses the database must include the
mysql::client profile in the docker-puppet config generation step.
By including the mysql::client profile in each containerized service, we ensure
that any change in configuration file will be reflected in the service's
/var/lib/config-data/{service}, and that paunch will restart the service's
container automatically.
We now only rely on MySQLClient from puppet/services, to make it possible to
generate /etc/my.cnf.d/tripleo.cnf on the host, and to set the hiera keys that
drive the generation of that config file in containers via docker-puppet.
We include a new YAML validation step to ensure that any service which depends
on MySQL will initialize the mysql::client profile during the docker-puppet
step.

This removes the default container names from all the templates
and uses a single environment file to specify the full container
name and registry from which to pull. Also does away with most
of DockerNamespace.

Makes it possible to resolve network subnets within a service
template; the data is transported into a new property ServiceData
wired into every service which hopefully is generic enough to
be extended in the future and transport more data.
Data can be consumed in service templates to set config values
which need to know what is the subnet where a deamon operates (for
example the Ceph Public vs Cluster network).

This solves a problem with bind-mounts when the containers are holding
files descriptors open.
At the same time this makes the template more robust to puppet changes
since new config files will be available in the containers without
needing to update the templates.

This commit consistently defines a heat template parameter in the form
of DockerXXXConfigImage where XXX represents the name of the
config_volume that is used by docker-puppet.
The goal is to mitigate hard to debug errors where the templates would
set different defaults for the image docker-puppet.py uses to run, for
the same config_volume name.
This fixes a couple of inconsistencies on the way.

Use common volumes, and use the host log dir in DB sync container.
