[ClusterLabs] Proposal for machine-friendly output from Pacemaker tools

There has been some discussion in the past about generating more
machine-friendly output from pacemaker CLI tools for scripting and
high-level interfaces, as well as possibly adding a pacemaker REST API.

I've filed an RFE BZ

 https://bugs.clusterlabs.org/show_bug.cgi?id=5376

to design an output interface that would suit these goals. An actual
REST API is not planned at this point, but this would provide a key
component of any future implementation.

The question is what machine-friendly output should look like. The
basic idea is: for commands like "crm_resource --constraints" or
"stonith_admin --history", what output format would be most useful for
a GUI or other program to parse?

Suggestions welcome here and/or on the bz ...
