Since OSA aims to do HA, it's important to run at least one copy of service at all times. Currently we do restart/run roles agaist all hosts inside a group for most of the services. This cause global service interruption if run without limit until service is restarted. To avoid this from happening, we add serial execution globally for all services with ability to override that behaviour. Change-Id: I5f6b8f9de32124a363cfe2c6191a4971f528cd70
