type Client 

type Client interface {
	GetValue(name Key, defaultValue interface{}) (interface{}, error)
	GetValueWithFilters(name Key, filters map[Filter]interface{}, defaultValue interface{}) (interface{}, error)

	GetIntValue(name Key, filters map[Filter]interface{}, defaultValue int) (int, error)
