> Modify AMS API layer to switch precision level based on query window.
> E.g.: Any query > 1 hour should get data from the 5 minute aggregate table unless
user provides a precision parameter.
> -startTime - endTime = 1 day OR precision = minutes
> implies query => 5 minute table
> -startTime - endTime = 3 hours and precision = seconds
> implies query => minute table (METRIC_RECORD)
> So, effectively we are just using the precision as guidance paramete
