enableRedisKeyspaceNotificationsInitializer return type InitializingBean

Previously RedisHttpSessionConfiguration
enableRedisKeyspaceNotificationsInitializer return type was a package
protected class. This meant if someone extended
RedisHttpSessionConfiguration they got IllegalAccessErrors.

This changes the return type to InitializingBean.

Fixes gh-109
