> It is observed that, even though *metricslimit* is set to 1500, maximum number of metrics
values retrieved is 1000. 
> This is due to, while creating EntityTable, metrics column family max version is specified
as 1000 which is hardcoded in {{EntityTable#DEFAULT_METRICS_MAX_VERSIONS}}. So, HBase will
return max version with following {{MIN(cf max version , user provided max version)}}. 
> This behavior is contradicting the documentation which claims that 
> {code}
> metricslimit - If specified, defines the number of metrics to return. Considered only
if fields contains METRICS/ALL or metricstoretrieve is specified. Ignored otherwise. The maximum
possible value for metricslimit can be maximum value of Integer. If it is not specified or
has a value less than 1, and metrics have to be retrieved, then metricslimit will be considered
as 1 i.e. latest single value of metric(s) will be returned.
