Add the class to upgrade the solr schema.

Add a smart test when we set the file name for the header of "content-deposition":
When the id doesn't end with the file extention, we set the file to be id+extension.

To set the content-deposition header, the cn will look the file name in the system metadata first.

Fix issue in getDefaultReplicationPolicy.

Previously, under some circumstances, a ReplicationPolicy was created but was missing the optional replicationAllowed and numReplicas attributes. These are critical to the policy, so ensure they are set to sensible defaults even when property parsing errors and other issues might skip them. Added a test of this method, but I note that other methods in SystemMetadataFactory do not have unit tests and should be added if they are modified.

Use the "MNRead" to replace "MNStorage" to determine the version of the MN.

Change an exception to more appropriate exception.

Add more checks to avoid a null exception.

Add more debug statement for deleting.

Add some information about pid on the log statement.
