AsconfWithAddAddress.seq - ASCONF chunk is received with Add IP Address Parameter which contain a valid address
To check that if ASCONF chunk is received with Add IP Address Parameter
which contain a valid address then the address specified should be added
to the existing association.

Association is established between endpoint A and B. Arrange the data
in endpoint A such that ASCONF message with Add IP Address Parameter
which contain a valid address address is sent to endpoint B.

TEST DESCRIPTION:
1. Send ASCONF chunk from endpoint A to B with Add IP Address Parameter
which contain a broadcast or multicast address.
2. Check A: ASCONF-ACK with No Error Cause should be received at
endpoint A. And endpoint B should consider the address part of the
existing association.

ASCONF-Request Correlation ID: 32 bits
This is an opaque integer assigned by the sender to identify each
request parameter. The receiver of the ASCONF Chunk will copy this
2-bit value into the ASCONF Response Correlation ID field of the
ASCONF-ACK response parameter. The sender of the ASCONF can use this
same value in the ASCONF-ACK to find which request the response is
for. Note that the receiver MUST NOT change this 32-bit value.
Address Parameter: TLV
This field contains an IPv4 or IPv6 address parameter as described in
Section 3.3.2.1 of [RFC4960]. The complete TLV is wrapped within
this parameter. It informs the receiver that the address specified
is to be added to the existing association. This parameter MUST NOT
contain a broadcast or multicast address. If the address 0.0.0.0 or
::0 is provided, the source address of the packet MUST be added.
