* Rename uploaded checkpoint to the new image;
* purge old edits file;
* rename edits.new to edits;
* redirect edit log streams to the new edits;
* update checkpoint time if the remote node is a checkpoint only node.

* @param sig
* @param remoteNNRole
* @throws IOException

void endCheckpoint(CheckpointSignature sig,
NamenodeRole remoteNNRole) throws IOException {
sig.validateStorageInfo(this);
