Clarification request: standardized "list" representation

[jnpkrn]

I'm just a messenger to deliver the necessity of standardizing upon the
(presumably machine processable) output from list actions, as discussed
in this pacemaker commit (therefore inviting @kgaillot to follow up here):

ClusterLabs/pacemaker@60ad773

By "standardizing", I'd imagine declaring the format explicitly in
https://github.com/ClusterLabs/fence-agents/blob/master/doc/FenceAgentAPI.md#agent-operations-and-return-values

Thanks

Agreed. For backward compatibility, I'd make it a recommendation than a requirement.

Separately but affecting the design here, we should come up with at least a recommendation on what characters are allowed in port names and aliases, possibly including escape sequences for special characters. Currently pacemaker only allows alphanumeric, dash, underbar, and dot, but there have been user requests for port names like "cs-rh7-1 [1/2]".
