A suggestion for the basic _config_get

Is there any reason not to include 
```
        'result': serialize_settings(node_addon, user)
```
in the default return value? 
Woops, missed this.
`ret` is the prefered name.

Any of the following are bad variable names, for various reasons.
* r
* cl
* cont
* args (Sometimes the variable and the pdb return will be the same for this, so its not terrible)
* rv
* c
* cont
* p
* up
* u
* down
* d
* w
* l
* where
* s
* set

etc.
