Damien Ciabrini fb88ed98a2 Check whether an HA resource already exists explicitly 
With ephemeral heat we lost the meaning of the 'stack_action' hiera key
which we previously used to distinguish between fresh deployment and
pre-existing deployment (aka redeploy).
Since this hiera key is not available anymore, in ansible we added a
TRIPLEO_HA_WRAPPER_RESOURCE_EXISTS env variable which will be true
when the resource existed even before calling puppet.

This way we can restore the previous behaviour (which was relying
on the stack_update hiera key) of restarting an HA
bundle on the bootstrap node in case of a configuration change.

While we're at it we make sure that the logging takes place via logger
so we're sure to capture these events in the journal.

Tested as follows:
1) Initial deploy:
[root@controller-0 ~]# journalctl |grep pcmkres
Sep 01 10:23:35 controller-0.alejandro.ftw pcmkrestart[47636]: Initial deployment, skipping the restart of haproxy-bundle
Sep 01 10:24:25 controller-0.alejandro.ftw pcmkrestart[49735]: Initial deployment, skipping the restart of galera-bundle
Sep 01 10:25:15 controller-0.alejandro.ftw pcmkrestart[53052]: Initial deployment, skipping the restart of rabbitmq-bundle
Sep 01 10:37:35 controller-0.alejandro.ftw pcmkrestart[148651]: Initial deployment, skipping the restart of openstack-cinder-volume

Redeploy changing only the haproxy config via a hiera key change:
Sep 01 11:12:29 controller-0.alejandro.ftw pcmkrestart[438507]: Wed Sep Restarting haproxy-bundle globally. Stopping:
Sep 01 11:12:37 controller-0.alejandro.ftw pcmkrestart[439271]: Wed Sep Restarting haproxy-bundle globally. Starting:
