Spring Boot Infinispan Persistence Add-On clashes with multiple CacheManagers

If a user declares `@EnableCaching` in their Spring application while using this add-on, the Infinispan Starter will create a new reference of `SpringRemoteCacheManager`.

This instance will clash with the user's defined `CacheManager`, ending in an exception during the application bootstrap.

Ideally, we should either block this bean creation, implement a CacheResolver, or document how users should deal with this scenario. They can either use Infinispan as their application data cache or they can mark their own CacheManager as Primary to use theirs.
