[bind10-dev] few configuration thoughts

[Jeremy C. Reed]

1) I think that configuration command names should match the executable 
names or maybe the name without the b10-prefix. Or allow both to work. 
For example: "stats-httpd show".

2) Lower case bindctl commands should work.

3) bindctl "help" should be more intuitive. For example these do not 
work:  "Stats help show" and "Stats show help". Jelte suggested: "help 
stats show".

4) bindctl should be able to show configurations in use. For example in 
the postfix world, "postconf" will report all the configurations 
(parameters and settings). And "postconf -n" will show just the 
custom settings.

 -n    Print  parameter  settings  that  are not left at their built-in
       default value, because they are explicitly specified in main.cf.

So even if no b10-config.db, I should be able to easily view 
configurations via bindctl. It is useful to see what is configured by 
default and what is custom configuration.

5) Boss components configurations should indicate msgq and sockcreator 
too? Maybe add to configuration but make it so not optional (they are 
mandatory).

6) When adding a single boss component, it shouldn't remove all the 
other components.  This happens with other maps or named_sets too. Maybe 
we need to design a new technique for this?
