InitWithCookiePre2.seq - INIT chunk is received with cookie preservative parameter (cookie life time not expire)
To check that if INIT chunk is received with cookie preservative parameter
then the endpoint should increment the life-span of the State Cookie in
milliseconds.

Association is not established between endpoint A and B. Arrange
data in endpoint A such that INIT chunk with Cookie Preservative
Parameter is sent to endpoint B.

TEST DESCRIPTION:
1. Attempt to make an association from endpoint A to endpoint B. Send
INIT message Cookie Preservative Parameter.
2. Check A: INIT message is accepted and INIT-ACK is sent from endpoint B.
3. Check B: The life-span of the State Cookie at endpoint B is incremented
in milliseconds.

3.3.2.1. Optional/Variable-Length Parameters in INIT
Cookie Preservative (9)
The sender of the INIT shall use this parameter to suggest to the
receiver of the INIT for a longer life-span of the State Cookie.

Suggested Cookie Life-Span Increment: 32 bits (unsigned integer)
This parameter indicates to the receiver how much increment in
milliseconds the sender wishes the receiver to add to its default
cookie life-span.
This optional parameter should be added to the INIT chunk by the
sender when it reattempts establishing an association with a peer
to which its previous attempt of establishing the association
failed due to a stale cookie operation error. The receiver MAY
choose to ignore the suggested cookie life-span increase for its
own security reasons.
