clean up logging for hz config file error
move hazelcast config file location code into the MetacatIndexServlet init method
correctly look up the context init parameter for the metacat properties file
lookup the hz client connection information from the hazelcast.xml file being used by metacat. https://projects.ecoinformatics.org/ecoinfo/issues/5909
add methods to set the SolrIndex instance and initialize the listener (includes overloaded constructor)
use SystemMetadata parameter for inserting into SolrIndex
add first pass at listening for SM events on HZ. Note that the configuration and even the call to solrIndex.insert() are not actually working.
Figured out to read beans from the configuration file.
