Add a metrics2 source for the Windows Azure Filesystem driver that was introduced with HADOOP-9629.

AzureFileSystemInstrumentation is the new MetricsSource.  

AzureNativeFilesystemStore and NativeAzureFilesystem have been modified to record statistics
and some machinery is added for the accumulation of 'rolling average' statistics.

Primary new code appears in org.apache.hadoop.fs.azure.metrics namespace.
