Soft Delete Ecto Repo

The goal is to support soft delete functionality in Ecto.Repo. With the suggestion by @imranismail, another repo is created and the remaining functionalities are delegate to the original MyApp.Repo.

The new repo get/2 and all/1 functions will exclude the soft deleted record by default. delete/1 and delete_all/1 will update the delete_at column by default instead of deleting.

Example

MyApp.Repo.get(MyApp.User, 1) //will return nil if record is in soft delete state
