Add name attribute at '@CacheNamespaceRef'

[kazuki43zoo]

I've allowed to specify a namespace by name instead of by type.

In this changes, we can share a cache object by name as follow:

Configuration configuration = new Configuration();
// ...
configuration.addCache(new PerpetualCache("masterCache"));
configuration.addMapper(CategoryMapper.class);
configuration.addMapper(ItemMapper.class);
// ...
SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(configuration);

@CacheNamespaceRef(name = "masterCache")
public interface CategoryMapper {
  // ...
}

@CacheNamespaceRef(name = "masterCache")
public interface ItemMapper {
  // ...
}

Please review this.

Hi @emacarron @harawata , What do you think about this changes ? If no problem, i will merge into master branch.

Nice work! Thank you, @kazuki43zoo !
Regarding the attribute name, 'namespace' might be clearer, but if you think 'name' is better, that's fine by me (BTW, the error message in the test case says 'namespace()').

Hi @harawata , Thanks for your review!!

Oh .. error message is mistaken ... (Good catch !!) -> fix via 26b5d2e
I've consider to use the namespace attribute at the first, but i felt redundant the namespace attribute into @CacheNamespaceRef. Hence; I've chose to use the name attribute in this change.
