HSEARCH-1692 Tighten up isolation of the Infinispan integration module
HSEARCH-1692 Aliasing to slot 5.0 of the backend 'backend-jms' is not necessary as it's an internal component
HSEARCH-1692 Set the TCCL (thread context classloader) to the Search/Infinispan integration module when parsing an Infinispan configuration file

This is needed to workaround limitations of the bootstrap process in Infinispan
HSEARCH-1692 Make sure our tests cover the need for setting the TCCL when starting Infinispan
