snf-ganeti-eventd doesn't automatically ensure it's running on the latest master node #267

Redacted email thread explaining the issue:

[me] wrote: While working on a wrapper tool for automating rolling reboots ..[snip].. after a master-failover, snf-ganeti-eventd needs to be manually stopped on the old master and started on the new master. This is not such an issue when manually wrangling a cluster, but becomes a show-stopper when automating the process ..[snip].. synnefo is not being an entirely "transparent" layer on Ganeti.

[Synnefo dev] wrote: you are right, currently you have to manually start the snf-ganeti-eventd daemon in the new Ganeti master. As you mention, because master-failover is not done automatically, this is not a big issue.

The problem is that master-failover does not run as a Ganeti job and Ganeti does not provide a hook to run in this case. ..[snip]..

Can you create an issue to track the progress of this feature ?

Also, I should mention that snf-ganeti-eventd can run in more than one master-candidate nodes, which however results in more messages to the RabbitMQ broker.
