-------------------------------------

Tested this patch during the weekend on a 200 node cluster (docker swarm). The cluster worked well. I fixed a few remaining configuration usage in the last patch.

> In HDFS-9847 introduced a new way to configure the time related configuration with using time unit in the vaule (eg. 10s, 5m, ...).
> Because the new behavior I have seen a lot of warning during my tests:
> {code}
> 2017-10-19 18:35:19,955 [main] INFO  Configuration.deprecation (Configuration.java:logDeprecation(1306)) - No unit for scm.container.client.idle.threshold(10000) assuming MILLISECONDS
> {code}
> So we need to add the time unit for every configuration. Unfortunately we have a few configuration parameter which includes the unit in the key name (eg dfs.cblock.block.buffer.flush.interval.seconds or ozone.container.report.interval.ms).
> I suggest to remove all the units from the key name and follow the new convention where any of the units could be used.
