[Feature Request] Create overloaded methods in DynamoDBMapper to set RequestMetricCollector for each operation

[swaranga]

We should have the ability to collect DynamoDB service call metrics even when using the DynamoDBMapper library. Note that while I can attach a client level RequestMetricCollector directly to the underlying DynamoDB client, this is not sufficient because I need to collect metrics based on calls to my service and having the ability to attach a metric collector at runtime is what solves the problem for me.

Related to #35

i'm not too sure if its directly related to #35

this feature request is not limited to DynamoDBMapper. in v1 all AwsClientBuilder and AmazonWebServiceRequest objects provided for the client to provide a RequestMetricCollector

v2 should provide for the same.

in fact this looks like more of a feature request to support sdk metrics in 2.0

Hi @SeekerWing we're tracking the work for clientside metrics here: #23

@dagnir thanks; apologies for duplication

Closing in favor of #35 and #23
