chore: remove deprecated default timeout from AbstractRedisClient (#3328) (#3344)

* chore: remove deprecated AbstractRedisClient#getDefaultTimeout
- remove usages from RedisClient and replaced with timeout value from redisUri
- fixed failing tests in RedisClientConnectIntegrationTests by asserting timeout to be equal to default timeout from RedisURI
- refactored DefaultRedisClient test fixture to not set timeout

* chore: remove deprecated default timeout from AbstractRedisClient
- refactor AtLeastOnce and AtMostOnce IntegrationTests to remove setting timeout on the client level and instead set it in the URI level
- removed default timeout and usages which set it from AbstractRedisClient, RedisClient and RedisClusterClient
