 * Hazelcast Permission type used in client protocol actions intended for Management Center operations. It has a similar
 * behavior as the {@link RuntimePermission} - i.e. actions are not used and the permission name can end with a wildcard
 * <code>".*"</code> (e.g. <code>"cluster.*"</code>).
 * <p>
 * The {@code "*"} (star character) or {@code null} used as the name means that such permission {@code implies} all other
 * {@link ManagementPermission} instances.
