features:
- A new variable has been added to allow a deployer to control
the restart of containers from common-tasks/os-lxc-container-setup.yml.
This new option is ``lxc_container_allow_restarts`` and has a
default of ``true``. If a deployer wishes to disable the
auto-restart functionality they can set this value to ``false``
and automatic container restarts will be disabled.
This is a complement to the same option already present in the
lxc_container_create role.
This option is useful to avoid uncoordinated restarts of galera
or rabbitmq containers if the LXC container configuration changes
in a way that requires a restart.
