Allow running hibernate-infinspan tests using Infinispan configuration specified by hibernate.cache.infinispan.cfg
Description
It is not currently possible to run all hibernate-infinspan tests using an Infinispan configuration specified by hibernate.cache.infinispan.cfg because:
1) some tests exclude properties provided by environment variables
2) some tests explicitly specify InfinispanRegionFactory.DEF_INFINISPAN_CONFIG_RESOURCE should be used
Both cause problems when running tests with Infinispan 7.2.1 because Hibernate's default configuration is for Infinispan 6.0.0.Final; Infinispan 7.2.1 does not provide backward-compatibility to that version configuration.
An Infinispan 7.2 configuration will be added as a test resource to 4.3 only.
In master, the default configuration has already been upgraded by and HHH-9781.
Environment
None
