[infinispan-dev] Singleton Cache Stores with Shared Cache Stores

Recently there was a start of a discussion regarding singleton cache stores
and how they behave. Interestingly according to our documentation  and
verification code  a singleton store cannot be used with a shared cache
store. This makes no sense to me as this means you would have a single
point of failure for your data. And also as Dan pointed out  there is
no Singleton cache loader to make sure all the loads are from the
coordinator either, which means you could have a read that returns null
despite it being in the store/loader.
And even looking at  it talks about singleton being used so not every
node writes to the underlying store, which implies it being shared.
I think we have enough proof to update this so a singleton store requires a
shared store, but I wanted to make sure we weren't missing something here.
