Improve StoreOptions use

[unaizorrilla]

Improve StoreOptions use to simplify change schemas, table etc without ceremony.

Started with #135

Moved to Esquio 4 because we are working on multiple stores and we address this issue at same time!

What else is needed for this? Should we make a way to setup the options via Configuration?

Well, the problem on this is about EF migrations, if you change the StoreOptions need also create a new migration to represent these changes!

I'm not sure at this moment how to simplify the customization of the schema without adding more code (migrations ) to do that!
