/**
 * Configuration for a custom {@link MemberAddressProvider} strategy.
 * 
 * The member address provider allows you to plug your own strategy to customize:
 * 

 * What address Hazelcast will bind to
 * What address Hazelcast will advertise to other members on which they can bind to
 * 
 * In most environments you don't need to customize this and the default strategy will work just
 * fine. However in some cloud environments the default strategy does not make the right choice and
 * the member address provider delegates the process of address picking to external code.
