Add properties attribute at '@CacheNamespace'

[kazuki43zoo]

I've allowed to inject property values to a custom cache implementation using annotation driven configuration.

In this changes, we can customize a custom cache implementation as follow:

@CacheNamespace(implementation = CustomCache.class, properties = {
    @Property(name = "stringValue", value = "bar")
    ,@Property(name = "integerValue", value = "99")
    ,@Property(name = "longValue", value = "9999")
})
public interface CustomCacheMapper {
    // ...
}

public class CustomCache implements Cache {
  // ...
  private String stringValue; // inject "bar"
  private Integer integerValue; // inject 99
  private long longValue; // inject 9999

  public CustomCache(String id) {
    this.id = id;
  }

  // setter/getter and implementation methods ..

}

And we can use placeholder as follow:

<properties>
    <property name="stringProperty" value="bar"/>
    <property name="integerProperty" value="99"/>
    <property name="longProperty" value="9999"/>
</properties>

@CacheNamespace(implementation = CustomCache.class, properties = {
    @Property(name = "stringValue", value = "${stringProperty}") // inject "bar"
    ,@Property(name = "integerValue", value = "${integerProperty}") // inject 99
    ,@Property(name = "longValue", value = "${longProperty}") // inject 9999
})
public interface CustomCacheMapper {
    // ...
}
