title: Spring JPA Specify entity's table name on the repository interface
body: <p>I have a scenario where I want to create multiple repositories for the same entity class. 
  The first and simplest scenario I want to save some of the instances of my class as rows in a different table than the primary table (which is designated on the entity itself). 
  other scenarios would be to create remote back ups hence the whole datasource would be different. 
  Does Spring allow things like that?</p>
