Idempotent cache key for function kwargs regardless of their order

[goredar]

Hi, there.

Currently, there is a cache miss when the order of function kwargs is not preserved during several calls. Tried to fix this behavior.

Looking forward to your reply.

Hi Vitaliy,

Thanks for your contribution. Your solution works well!

The only drawback is that the sorting will slow down the make_key function a little bit (~10%). Since it is not a common practice to call a function multiple times with its kwargs in different order, I will add an option to the @cached decorator so that users can decide whether they need this feature.

Cheers!
