Provide a way to use Flags without resorting to a ThreadLocal
-------------------------------------------------------------

                 Key: ISPN-1309
                 URL: https://issues.jboss.org/browse/ISPN-1309
             Project: Infinispan
          Issue Type: Feature Request
            Reporter: Sanne Grinovero
            Assignee: Manik Surtani
             Fix For: 6.0.0.FINAL


A brief performance analysis highlighted a significant impact on performance because of the use of ThreadLocals to hold the enabled flags in the current context.

We should check these findings with a proper test and provide an alternative way, ideally one which doesn't need to lookup in the flagHolder either (avoid both the put and the get in the threadlocal).

We'll need a method which returns a new Cache instance having the mentioned Flags always implicitly added to the invocation context. I think it would be fine in such an alternative implementation to not support dynamic flags.
