containers do not automatically restart if killed

[Alex Schultz]

Under docker-1.13.1-53.git774336d.el7.centos.x86_64 on centos/rhel, kolla containers do not automatically restart if killed. In researching this issue, it appears to be because with this version of docker the lack of a STOPSIGNAL in the Dockerfiles built by Kolla . By adding the STOPSIGNAL SIGTERM to the containers and rebuilding them, containers will properly restart if they are killed.

    Add in a STOPSIGNAL configuration

    For docker 1.13.1, if STOPSIGNAL is not provided in the docker image,
    the container will not automatically restart the container. It might be
    better to define this in the Kolla scripts as a configuration option for
    each container, but I'm unsure if it's a problem for any other version
    so it might be best to configure this in tripleo until a newer version
    of docker is consumed. Additionally I'm not sure if any of the
    containers would need something other than STOPSIGNAL SIGTERM which
    should be the default if none is provided.
