When listing parameters for an environment, add an option that only
shows parameters set in the environment itself. This will allow ks users
to show only the differences. The new option is `--without-modules`.

example:

```
 $ ks param list --env default
COMPONENT     PARAM   VALUE
=========     =====   =====
nested.redis3 envset  1
redis         envset  1
redis2        envset  1
redis2        name    'redis2'
redis2        values  {}
redis2        version '3.7.3'
$ ks param list --env default --without-modules
COMPONENT     PARAM  VALUE
=========     =====  =====
nested.redis3 envset 1
redis         envset 1
redis2        envset 1
```

Fixes #747
