Decode the string of the uri after we break the uri into parts base on the "/".

Use the D1NodeVersionChecker to determine the mn's version rather than using ping.

When the cn.notifyReplicaNodes method, if the target MN source code is a v2 mn, we will use v2 api; if it is a v1 node, we will use v1 api.

A new class is used to get the version of service for a given node.

Only support the application/bagit format in the getPackage method.

Use the status of mn.ping to guess the version of the source node in the replicate method.

In the replicate method, it will use the v1.getReplica method if the source node only supports v1 replication service.

The code was added to compare the serial version in the updateSystemMetadata method. If the serial version in the new system metadata is less than or equals previous version, an exception will be thrown.

Increase the version number after updating the existing object's system metadata in the update method.
