/**
 * @brief adds an address to the client.
 *
 * Adds a single address to the client. If the client is not present in
 * address manager, adds it, too. Also, if client's IA is missing, adds it as well.
 *
 * @param clntDuid client DUID
 * @param clntAddr client's address (link-local, used if unicast is to be used)
 * @param iface interface, on which client is reachable
 * @param IAID ID of an IA
 * @param T1 - T1 timer
 * @param T2 - T2 timer
 * @param addr - address to be added
 * @param pref preferred lifetime
 * @param valid valid lifetime
 * @param quiet quiet mode (e.g. used during SOLICIT handling, don't print anything about
 *              adding client/IA/address, as it will be deleted immediately anyway)
 *
 * @return true, if addition was successful
