Describe the bug

RemoteCacheManager.findConfiguration(String) iterates over the Map<String, RemoteCacheConfiguration> returned via Configuration.remoteCaches().
As of ~~ISPN-11960~~, this map may be modified after the Configuration is created, and so iterate over this map requires exclusive access.
If another thread calls Configuration.addRemoteCache(...), a concurrent call to RemoteCacheManager.getCache(...) will fail with the following:

ISPN000660: Cache HotRodPersistentTimerServiceTestCase.war.AutoTransientTimerBean.PERSISTENT start failed, stopping any running components: org.infinispan.commons.CacheConfigurationException: ISPN000659: Component ComponentWrapper{name=org.infinispan.persistence.manager.PersistenceManager, instance=org.infinispan.persistence.manager.PersistenceManagerImpl@2e8de287, status=FAILED} failed to start
