> This adds a new timeline store plugin that is intended as a stop-gap measure to mitigate
some of the issues we've seen with ATS v1 while waiting for ATS v2.  The intent of this plugin
is to provide a workable solution for running the Tez UI against the timeline server on a
large-scale clusters running many thousands of jobs per day.
