Support BIRD syntax for BGP AS Path & Communities

[jb3]

Feature Description

Communities

BIRD represents BGP communities as a tuple of integers, for example the community 64511:1 is represented as (64511, 1). To fetch all routes matching this a query such as show route where (65517, 1) ~ bgp_community all. It would be nice to be able to translate colon notation for BGP communities into these bird queries.

AS Path

Similarly, to find all routes where the specified ASN is present in the AS-Path, the bird query looks like sh ro where 15169 ~ bgp_path all. Translation from syntax such as _15169$, _15169_, $15169_ and so on would be a nice feature to have.

Environment & Use Case

This feature request only applies to having BIRD as a NOS.
