Subject: [PATCH] Add alexandria url prefix to identifier for OAI

This adds a url prefix to the identifier element in the
OAI-PMH feed. The rules in Primo are setup so that they
check for the http prefix to create links.

This creates a configuration option to set the prefix and
concats the prefix to existing identifier element in the solr
document via the `ObjectIndexer`.
