Add option to force toggles from command line during startup

[solj]

Currently, the only way to turn on debugging for various plugins is by toggling the debug variable via bcfg2-admin xcmd while the server is running. We need to add a way to do this during server startup.

11:27 < desai> toggle_debug only works if the server will authenticate the xcmd
11:28 < desai> so here is the thing to do
11:28 < desai> first grab the traceback from that permission denied
11:28 < desai> then comment out the parts of bcfg2.conf for the ca and cert
11:28 < desai> then run the toggle_debug
11:28 < desai> then uncomment out the bcfg2 bits
11:29 < desai> and then run the xcmd again and collect the trace from the authentication failure
11:29 < desai> solj: we also need a way to force the toggles from the command line at startup
11:35 < solj> desai: k, i'll create a ticket
