Kube-router: Support more than a single AS per cluster to allow AS per rack design

[SEJeff]

In specific, this project calico document shows a really common design that network engineers really like for these sorts of things. I'd like to use kube-router, but can't due to it not supporting this.

This involves each rack using a different AS

Thanks @SEJeff i will see how best we can incorporate that support.

@murali-reddy I think this falls under the same design goals but I just want to explicitly state it; we would also like to peer with different external BGP routers either via metadata or statically defined.

[murali-reddy]

thanks @jdconti for the inputs i will work towards flexible model to support multiple AS.

sorry did not get enough time to look in this issue, will try to get this sorted out and implement early next week

@SEJeff @jdconti please see the documentation, please open a bug if you run into any issue.

Fantastic stuff and that looks like a very clean implementation. Thanks @murali-reddy !

This looks a lot lighterweight than Calico.
