Remove "spring.cache.hazelcast.config" #8470
Description
Currently we support the use case of auto-configuring a separate HazelcastInstance for caching purposes on top of the general hazelcast auto-configuration.
That complexifie the code a lot and reusing the existing HazelcastInstance is what we should do, leaving such advanced use cases to a dedicated CacheManager bean declaration in user's configuration.
This should also simply further work on Hazelcast. We should deprecate the property in 1.5
