Reuse the rust caches

[Desiki-high]

See rust cache, the rust cache key is base on thejob default.

And the caches is approaching total cache storage limit. We have too many rust caches:

So maybe we can reuse these caches by shared-key like Swatinem/rust-cache#127?

Maybe the cache can be reused across jobs.

We might be able to use the same version rust-cache. For example, uniformly adjusted to Swatinem/rust-cache@v2 in the yaml file.

nydus-build and nydus-build-master can easily reuse the same cache because of the same dependences. But nydus-unit-test and nydus-unit-test-coverage maybe have different dependences, so if we use the rust cache uploaded by nydus-unit-test can not accelerate the nydus build?

Maybe we can only reuse the rust caches between nydus-build and nydus-build-master in smoke and benchmark?

Should be ok.
