Lower allocation cost of instances of org.infinispan.commands.read.GetKeyValueCommand

Classes of type

org.infinispan.commands.read.GetKeyValueCommand

have an high cost in terms of memory allocation.

Would be great if we could reduce the runtime cost: in an app server test of just 25 minutes - which is stressing way more systems than just Infinispan - just the occasional get operations 43GB of memory accumulated over time.

This is a high cost on the TLABs, skewing various other values, among others making the default GC options unsuitable.
