With Spring Session Data Geode module being removed from the BOM, all of Spring Session's modules are now managed by this repository.
This means that the BOM itself can be moved to this repository, in order to simplify the overall project maintenance.

This commit restructures configuration support for Redis-backed
HttpSession with aim to enable users to easily select the
SessionRepository implementation they prefer to use.
This is achieved by introducing [at]EnableRedisIndexedHttpSession
annotation that can be used to configure RedisIndexedSessionRepository,
while the existing [at]EnableRedisHttpSession will going forward
configure RedisSessionRepository as the SessionRepository implementation
used by Spring Session.
Additionally, this also introduces AbstractRedisHttpSessionConfiguration
as the base configuration class that manages common aspects of
Redis-backed HttpSession support, which is then extended by more
specific configuration classes that provide specific SessionRepository
implementation.
Closes gh-2122
