Align Redis deprecations with RedisAPI methods

[aviadlevy]

Describe the feature

Some Redis commands are marked as deprecated.
I think it'll be good to add deprecation notice to methods in this library that Redis marked as deprecated

Use cases

Help developers better decide which method to use and make code that will last longer.

Contribution

Since this is seems like not an urgent task and only "documentation" I'm happy to try do it myself (but it might take some time since it's quite busy days for me 😓 )
