Naming on Cached trait

[Stargateur]

All method on the Cached trait are named cache_*, it's very redundant. I think we should remove this noise.

[jaemk]

I guess it's a bit redundant, but at least means you never need to disambiguate the calls with "fully qualified call syntax"

[Stargateur]

I see no case where a disambiguate call would be needed in practice on the cache of Cached.

[jaemk]

I'd be open to phasing in methods without the cache prefix and having their default implementations call the existing cache_ methods until they are removed in the future.

[Stargateur]

Problem is if we just add new method this will make implementation annoying, and if we ship it as provided method, this will still be a hard breaking change. If we do the other way around, making actual method provided method. This would allow a better soft breaking change.

Unless you feel strong about or we have more people thinking like me I will let this issue open until people that used this crate agree or not.
