Create a new {@code ConcurrentReferenceHashMap} instance.

@param initialCapacity  the initial capacity of the map
@param loadFactor       the load factor. When the average number of references per
                        table exceeds this value, resize will be attempted.
@param concurrencyLevel the expected number of threads that will concurrently
                        write to the map
@param referenceType    the reference type used for entries (soft or weak)
