Give SolrLocator the ability to handle managed schemas.

This gives SolrLocator the ability to handle managed schemas, which don't have a "schema.xml" file.

Changes:
- Most of the changes are just solr configuration files copied from the existing config to a new config
- Modified the new configs to use ManagedSchema
- Generated a ManagedSchema schema file from my cluster, called managed-schema-for-morphlines.  I did add the Copyright stuff to not hit the rat checks
- Changed SolrLocator to not build the schema the same way as a SolrCore via the IndexSchemaFactory
- Added a test for managed schema that fails if the change to SolrLocator is not present
