Adds a step0 for any pre-upgrade checks. This migrates
some of the checks we have at the top of
extraconfig/tasks/major_upgrade_controller_pacemaker_1.sh
Checks for other services (and for the cluster) will follow
in separate commits.

When a service connects to the database VIP from the node hosting this
VIP, the resulting TCP socket has a src address which is by default
bound to the VIP as well. If the VIP is failed over to another node
while the socket's Send-Q is not empty, TCP keepalive won't engage and
the service will become unavailable for a very long time (by default
more than 10m).
To prevent failover issues, DB connections should have the src address
of their TCP socket bound to the IP of the network interface used for
MySQL traffic. This is achieved by passing a new option to the
database connection URIs. This option is available starting from
PyMySQL 0.7.9-2.
We use a new intermediate variable in hiera to hold the IP to be used
as a source address for all DB connections. All services adapt their
database URI accordingly.
Moreover, a new YAML validation check is added to guarantee that new
services will construct their database URI appropriately.

Heat now supports release name aliases, so we can replace
the inconsistent mix of date related versions with one consistent
version that aligns with the supported version of heat for this
t-h-t branch.
This should also help new users who sometimes copy/paste old templates
and discover intrinsic functions in the t-h-t docs don't work because
their template version is too old.

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.

This changes how we get the network-based FQDNs for the specific
services, from using the custom fact, to the new hiera entries.

This patch optimizes how we deploy hiera by using a new
heat hook specifically designed to help compose hiera
within heat templates. As part of this change:
- we update all the 'hiera' software configurations to set the group to hiera
instead of os-apply-config.
- The new format uses JSON instead of YAML. The hook actually writes
out the hiera JSON directly so no conversion takes place. Arrays,
Strings, Booleans all stay in their native formats. As such we can avoid
having to do many of the awkward string and list conversions in t-h-t to
support the previous YAML formatting.
- The new hook prefers JSON over YAML so upgrading users will have the
new files prefered. (we will post a cleanup routine for the old files
soon but this isn't a new behavior, JSON is now simply prefered.)
- A lot of services required edits to account for default settings that
worked in YAML that no longer work correctly in the native JSON
format. In almost all these cases I think the resulting codes looks
cleaner and is more explicit with regards to what is getting
configured in hiera on the actual nodes.

This adds the necessary hieradata for enabling TLS for MySQL (which
happens to run on the internal network). It also adds a template so
this can be done via certmonger. As with other services, this will
fill the necessary specs for the certificate to be requested in a
hash that will be consumed in puppet-tripleo.
Note that this only enables that we can now use TLS, however, we still
need to configure the services (or limit the users the services use)
to only connect via SSL. But that will be done in another patch, as
there is some things that need to land before we can do this (changes
in puppetlabs-mysql and puppet-openstacklib).

This now takes into use the mysql_bind_host key, to set an
appropriate fqdn for mysql to bind to.

This moves the config settings out of controller.yaml for MySQL
and into puppet/services/database/mysql.yaml.
The top leve MysqlRootPassword is still maintained by default
in overcloud.yaml so that users who upgrade won't get
broken. New users may optionally specify the MysqlRootPassword
as a parameter instead which will take priority over the top
level generated parameter.
We drop the top level MysqlClusterUniquePart because it is no
longer used (I think it was a remnant from t-i-e).

This patch adds a new DefaultPasswords parameter to
composable services. This is needed to help provide
access to top level password resources that overcloud.yaml
currently manages (passwords for Rabbit, Mysql, etc.).
Moving the RandomString resources into composable services
would cause them to regenerate within the stack. With this
approach we can leave them where they are while we deprecate
the top level mechanism and move the code that uses the
passwords into the composable services.

This will be needed to pick the network where the service has
to bind to from within the service template.

This patch adds a new service_name section to each composable
service. We now have an explicit unit test check to ensure that
service_name exists in tools/yaml-validate.py.
This patch also wires service_names into hieradata on each
of the roles so that tools can access the deployed services locally
during deployment and upgrades.

This patch just moves the Puppet code into puppet-tripleo.
A future iteration will be to move parameters within the service
template.
