Hello,

the command "pcs resource list" produces a traceback after a few 10s of seconds of high CPU usage and no useful output appears.
A very similar traceback happens for "pcs stonith list" (but I think that's because they share the same code as stonith devices are primitives themselves),

Reproducible: Always

Steps to Reproduce:
1. Install the cluster components pcs pacemaker
2. Create a basic cluster
3. Run "pcs resource list" or "pcs stonith list"
4. If you manage the cluster via pcsd web ui or cockpit, you can list resource types
Actual Results:
For "pcs resource list":
