Display BGP gateway mode in show protocol output

[David Petera]

Hello Sébastien!

Thanks for sending us these patches, but unfortunately it would *not* be 
wise to change BIRD's CLI output right now.

We discussed it in our team and the the primary reason is this:

Since BIRD does not yet have well defined API for communication, most 
automation and tooling around BIRD (including our own) relies on the 
exact format of the CLI output.
These changes would/could break the tooling around BIRD and cause lot of 
headache for little gain.

We know that this situation is not ideal and thus API for BIRD is being 
worked on.
Once finished we can improve the CLI output without major consequences.

Hope you understand, why we can not accept these patches right now.

Wish you a great weekend and happy routing!
David
