HADOOP-12746. ReconfigurableBase should update the cached configuration
Initial patch to have ReconfigurableBase#ReconfigurationThread update
parent's cached configuration.
The effective value may be different from the passed in newVal so this
patch also updates ReconfigurableBase#reconfigurePropertyImpl to return the
effective config value. This idea was suggested by [~eddyxu] on
https://issues.apache.org/jira/secure/EditComment!default.jspa?id=12740232&commentId=15118434
Will likely add more unit tests for this.
