feature #173 Add configuration of root namespace (Sergey Rabochiy, weaverryan)

This PR was merged into the 1.0-dev branch.

Discussion
----------

Add configuration of root namespace

This PR adds configuration for namespaces used in `make:*` commands that was discussed in #133.
I've used [this doc](https://symfony.com/doc/current/bundles/configuration.html) in work and examples from `FrameworkBundle`.

New parameter:
`maker.root_namespace` - application root namespace, default: `App`

To change it, you should create configuration file in `config/packages/dev` with name `maker.yaml` or `maker.xml` or `maker.php` with root node `maker`. For example YAML file:
```yaml
# config/packages/dev/maker.yaml
maker:
    root_namespace: 'App'
```

I've added some tests. I think we don't need Flex recipe but just document new feature.
I need help for write documentation because my English.
