### Description of PR
[HDFS-16949](https://issues.apache.org/jira/browse/HDFS-16949) introduced
InverseQuantiles. However during snapshot for Inverse Quantiles we were still
trying to access values from previous snapshot based on the Quantile Array
declared in MutableQuantiles. ( Quantile(.50, .050), Quantile(.75, .025),
Quantile(.90, .010), Quantile(.95, .005), Quantile(.99, .001) )
For InverseQuantiles we wont have these values ( except for Quantile(.50,
.050) ) thus except for 50 Percentile snapshot wont return any value for the
remaining quantiles.
Fix is to use the correct Quantiles Array to retrieve values during
snapshot. The new UTs verify this behavior.
### How was this patch tested?
Added new UTs verifying the fix ( and fail without it )
