lib: mgmtd: fix debug cli commands and memleaks

- Cannot have 2 cmd_node's with same .node number. Install the mgmtd
client library debug nodes (client frontend and client backend) using
new unique node numbers. Fixes memleaks.

- Fix "debug mgmt client backend" to generate correct config (and not
for frontend).
