Feature/metrics-timeresolution-support

Test cases for having Time series table with resolution for a minute and bug fixes to support that.

Time series table previously just writes the new data as we only tested resolution with a second, with minute aggregation , we would want to add to the previous timestamp if an entry exists and the metric type is counter, so added increment support in the time series table.

the method is to save a list of records, the client specifies it wants to save the records and based on the record type we either increment or do a put. @abaranau also suggested we would move this to read less increment , in which case the increment will also be a put.
