Do we need to make `dfs.blockreport.initialDelay` reconfiguable?
Thanks @tasanuma for your comments.
`dfs.blockreport.initialDelay` used in `BPServiceActor#register`. In some
cases (the Namenode is stuck), the DN will heartbeat out and become a deadnode,
but the process may be alive. When the exception is recovered, the datanode may
need to register again, which triggers `BPServiceActor#register`. In this case,
making `dfs.blockreport.initialDelay` reconfiguable is a little effect.
