Bug Description

It is typically not desirable to use public ASN for a cluster.
However there is a need to interoperate with an L3VPN core that
uses a 4-byte AS.

Hence the first phase of the implementation would be to handle
received AS4_PATH attribute and prepend our AS to it. Second
phase would be to allow a 4-byte AS as the local AS for cluster.

https://tools.ietf.org/html/rfc6793

Note that 4 byte AS support is not necessary even if the underlay
uses 4 byte ASes as described below. No interaction is required
between the underlay and the overlay.

Contrail to support 4 byte AS

Contrail only supports 2 byte AS today. There is a requirement to extend
it to use 4 byte AS also.
This is first draft to support the same. Some testcaes are added and
some more may need to be added.

Changing asn range to 32bit values

$byte ASN support was added recently. Need to reflect the same in
schema also.
