Change in ovirt-engine[master]: core:Power Management: restart operatio..(#865385)

Eli Mesika has submitted this change and it was merged. Change subject: core:Power Management: restart operatio..(#865385) ...................................................................... core:Power Management: restart operatio..(#865385) core:Power Management: restart operation fails occasionally Currently we are performing the following in the Restart command 1) send Stop command to the fence agent 2) wait for 'off' status by sampling the agent status command 3) send Start command to the fence agent 4) wait for 'on' status by sampling the agent status command There are some cases in which the Start command can fail but the engine will still try to get the 'on' status and give up after the configured retries. The reason is that the Start & Stop command are async and we only get success for the fence script invocation. In the case that the Agent & Host uses the same power supply the Start may fail, therefor we had decided that in any case that we fail to Start the Host after the configurable retries, we will send additional Start command to cover such a case.
