Simon Baslé 6d9a2eb9b8 Improve fix of duplicate upstream subscription during reactive cache put ...

This commit fixes an issue where a Cacheable method which returns a
Flux (or multi-value publisher) will be invoked once, but the returned
publisher is actually subscribed twice.

The previous fix 988f3630c would cause the cached elements to depend on
the first usage pattern / request pattern, which is likely to be too
confusing to users. This fix reintroduces the notion of exhausting the
original Flux by having a second subscriber dedicated to that, but uses
`refCount(2)` to ensure that the original `Flux` returned by the cached
method is still only subscribed once.

Closes gh-32370
