MetadataProvider is implemented by each platform in a platform specific manner. It can process metadata stored in ChaincodeDeploymentSpec in different formats. The common format is targz. Currently users expect the metadata to be presented as tar file entries (directly extracted from chaincode stored in targz format). In future, we would like provide better abstraction by extending the interface
