STORM-1941 Nimbus discovery can fail when zookeeper reconnect happens. (1.x)
* delete ephemeral node first when reconnected handler is called
This also deletes node if session is alive but reconnected.
If we really need to avoid deleting node, we could check ephemeral owner
before deleting. Zookeeper reconnect is not happening so often, so I guess it's
fine to not applying. If you think we should, please let me know.
Btw, blobstore also uses ephemeral nodes so I'm curious they should be
recreated too.
