Add generate content-entity command

[vacho]

This is a issue for requirement of a new feature

This feature complement the 'generate entity' recently added by @jmolivas at Merge pull request #142 which generate 'configuration-entity'

[jmolivas]

This sounds great we may use this as a reference https://www.drupal.org/node/2192175

Do you see this new functionality as:

• Same command generate:entity and ask for entity type then take decisions based on this value
• Two separated commands generate:entity:configuration and generate:entity:content

[dmouse]

I think that we should separate the entity commands and avoid have much logic in a single command

I like the idea of separate them, since we will avoid having logic in one single command and within template files

[vacho]

Yes I agree that maintain the code as simple as possible.

At the time I was programmed using the same command and adding logic to discern at EntityGenerator.php

But I can do to separate the commands. Let's see when I apply Pull Request

@vacho be aware class name changed take a look at #150

src/Command/GeneratorEntityCommand.php → src/Command/GeneratorEntityConfigCommand.php
src/Generator/EntityGenerator.php → src/Generator/EntityConfigGenerator.php

very good decision and action.

Right now in my branch "content-entities" can be created. Now it

1. Update my branch there and make it work.
2. Perform a battery of tests.
3. Perform pull request.

I go for that.
