IMPALA-9829: Add metrics for Spilling to S3

Three types of metrics are added in disk-io-mgr :
1. impala-server.io-mgr.queue--bash.write-latency, unit: ns
2. impala-server.io-mgr.queue--bash.write-size, unit: Bytes
3. impala-server.io-mgr.queue--bash.write-io-error

It is a mock function for spill to s3, more test cases will be added later when 
it is fully functional.
