use rpki-client 'expires' functionality in openbgpd output

[job]

Hi @pierky

Starting with OpenBGPD 7.2, the bgpd.conf configuration format permits to specify an optional expiration moment (as unix timestamp) for each RPKI VRP. This makes it possible to automatically purge outdated RPKI information from the routeserver pipeline, in case arouteserver's configuration generation process is stuck or not running.

The format is pretty straight forward:

roa-set {
        1.0.0.0/24 source-as 13335 expires 1639189098
        1.0.4.0/24 source-as 38803 expires 1639180474
        1.0.4.0/22 source-as 38803 expires 1639180474
        ...
}

Values can be extracted from rpki-client's output (example is at vrps.json)

Perhaps arouteserver should take advantage of this OpenBGPD capability and pass on these expiration moments?

Hi @job,

thanks for the suggestion. I’ve added the support of the expires attribute: a pre-release is out on the test instance of PyPi: v1.13.0-alpha1

It'd be great if you could give it a try, by following the instructions reported on the docs about how to install pre-releases: https://arouteserver.readthedocs.io/en/latest/INSTALLATION.html#development-and-pre-release-versions

Pls let me know if you have a chance to try it out.

Thanks

@pierky tested - looks good to me

Thanks @job, the pipeline for v1.13.0 is running, if everything goes well, the new release will be out in about 1 hour from now.
