When fixing LP#1643487 we added ?bind_address to all DB URIs.
Since this clashes with Cellsv2 due to the URIs becoming host
dependent, we need a new approach to pass bind_address to pymysql
that leaves the DB URIs host-independent.
In change Iff8bd2d9ee85f7bb1445aa2e1b3cfbff1f397b18 we first create a
/etc/my.cnf.d/tripleo.cnf file with a [tripleo] section with the correct
bind-address option.
In this change we make sure that the DB URIs will point to the added
file and to the specific section containing the necessary bind-address
option. We do introduce a new MySQLClient profile which will hold all
this more client-specific configuration so that this change can fit
better in the composable roles work. Also, in the future it might
contain the necessary configuration for SSL for example.
Note that in case the /etc/my.cnf.d/tripleo.cnf file does not exist
(because it is created via the mysqlclient profile), things keep on
working as usual and the bind-address option simply won't be set, which
has no impact on hosts where there are no VIPs.

The admin endpoint is listening on the ctlplane network by default;
services should ideally be using the internal api network for this kind
of traffic, as the ctlplane network is mostly for provisioning. On the
other hand, the admin endpoint shouldn't be as relevant with services
switching to keystone v3.

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 integrates panko service api into tripleo heat templates.
By default, we will disable this service, an environment service
file is included to enable if needed.
