[c-nsp] automatically enable debugs after a reload

[Masood Ahmad Shah]

For example, to enable debugging of incoming SSH connections, use the
following EEM applet:

event manager applet EnableDebugging
event syslog occurs 1 pattern "%SYS-5-RESTART"
action 1.0 cli command "enable"
action 2.0 cli command "debug ip ssh"

For versions of IOS that don't support EEM but do support the config command
'do', you could modify the config off of the router and add a 'do debug...'
command to the end then copy the config back directly into the
startup-config. It's messy I know, but it does work.

I'm trying to check if CSCed45578 applies to our case, but the first tests
show that the proposed workaround doesn't work.
