> Ozone: Support CopyContainer

> Once a container is closed we need to copy the container to the correct pool 
> or re-encode the container to use erasure coding. The copyContainer allows 
> users to get the container as a tarball from the remote machine.
> The copyContainer is a basic step to move the raw container data from one 
> datanode to an other node. It could be used by higher level components such 
> like the scm which ensures that the replication rules are satisfied.
> The CopyContainer by default works in pull model: the destination datanode 
> could read the raw data from one or more source datanode where the container 
> exists.
> The source provides a binary representation of the container over a common 
> interface which has two method:
>  # prepare(containerName)
>  # copyData(String containerName, OutputStream destination)
> Prepare phase is called right after the closing event and the implementation 
> could prepare for the copy by precreate a compressed tar file from the 
> container data. As a first step we can provide a simple implementation which 
> creates the tar files on demand.
> The destination datanode should retry the copy if the container in the source 
> node not yet prepared.
> The raw container data is provided over HTTP. The HTTP endpoint should be 
> separated from the ObjectStore  REST API (similar to the distinctions between 
> HDFS-7240 and HDFS-13074) 
> Long-term the HTTP endpoint should support Http-Range requests: One container 
> could be copied from multiple source by the destination.
