Metacat

The location of the solr index needs to be configured and the default should be: /var/metacat/solr
All three components need to know about this location (metacat-index and Metacat will both be using the Embedded Solr client and SOLR needs to know where its index is.
Additionally, the metacat-index project needs to know what the Hazelcast client connection properties are so that it can listen to events on those shared structures.
We may also want metacat-index to have direct read-only access to the Metacat DB in which case we would want it to have access to the metacat.properties file.

I think the easiest thing to do is to configure everything in metacat.properties and then point the components to metacat.properties to read the values it needs.
