Extend properties for `RedisSentinelConfiguration`

[mustaphazorgati]

While using the RedisSentinelConfiguration (reference: https://docs.spring.io/spring-data/redis/reference/redis/connection-modes.html#redis:sentinel), we discovered that the RedisSentinelConfiguration class has more configuration options that can be configured than the current set of properties.

In this issue, we want to extend the properties so that the RedisSentinelConfiguration can be fully configured via PropertySource.
