bgpd: add hooks for displaying debug information of a plugin

Browse Source 
when a plugin is attached, some debugs may be attached to that plugin.
For that, add one hook that is interacting with vty: a boolean indicates
what the usage is for: either for impacting the 'show running-config',
or for impacting the 'show debugging' command.
