Cache when and unless

[devajmeireles]

Since if I suggest the PR it will be disapproved 😂 , I'm posting it here for those who want to do it:

It would be awesome if Cache facade supported the when and unless methods, to provide us with something like this:

Cache::when(/* ... */, fn (Cache $cache) => $cache->rememberForever($key, fn() => $post))

In theory is just to add the Conditionable trait to the Cache repository.

Conditionable returns $this. I don't see any benefits. For one-liner fun there is a way to avoid of using if in less keystrokes:

/* ... */ && Cache::rememberForever($key, fn() => $post))
