Template string to be used to generate instance names.

This template controls the creation of the database name of an instance. This
is *not* the display name you enter when creating an instance (via Horizon
or CLI). For a new deployment it is advisable to change the default value
(which uses the database autoincrement) to another value which makes use
of the attributes of an instance, like ``instance-%(uuid)s``. If you
already have instances in your deployment when you change this, your
deployment will break.

Possible values:

* A string which either uses the instance database ID (like the
  default)
* A string with a list of named database columns, for example ``%(id)d``
  or ``%(uuid)s`` or ``%(hostname)s``.
