osaf: improve response time in etcd3.plugin [#3016]
if the initial call to watch takeover request in etcd3.plugin
is made when etcd has already been shutdown (for example,
when etcd is running locally and the node is being shutdown),
the plugin should return 0 with a fake takeover request to ensure
rded shuts down promptly. Otherwise, it will keep calling
watch, delaying node shutdown.

** [tickets:#3016] osaf: etcd3.plugin slows down cluster shutdown**
**Status:** fixed
**Milestone:** 5.19.03
**Created:** Thu Mar 07, 2019 06:29 AM UTC by Gary Lee
**Last Updated:** Tue Mar 12, 2019 12:39 AM UTC
**Owner:** Gary Lee
During a cluster shutdown, if the active SC is shutdown first, then the standby
SC becomes active if etcd is still up. If etcd is then shutdown, the newly
active SC may take a long time to shutdown when it's executing 'watch
takeover_request' while etcd is down.
