Support simple cache optimization in Infinispan subsystem

Infinispan 8.0.1.Final includes a new simple cache, that is effectively a local cache without an interceptor stack, and thus without support for transactions, persistence, etc.

Unfortunately, the configuration of such a cache in Infinispan is sloppy. A simple cache is configured by a single boolean attribute, which of course means that all kinds of invalid configuration combinations are possible. Ideally, a simple cache configuration should only expose relevant configuration aspects. I propose we create a new cache type like so:

<simple-cache name="...">
   <eviction .../>
   <expiration .../>
</simple-cache>

The fact that this doesn't translate into a designated cache mode is irrelevant.
