Handling unreliable proxy partners

>  Use "rlm_always".   From the Changelog for 3.0.22:

        * New xlat for setting status of rlm_always instances and new
          resource-check example virtual server for manipulating control flow
          in unlang policies based on status of some external resource.
          Patches from Terry Burton.

Ah - looks promising

I'd better go and re-read the 3.0.22 release notes and check what other new toys I've missed.

Thanks.
