[infinispan-dev] Changes to the Command interfaces

[Manik Surtani]

In the light of https://jira.jboss.org/jira/browse/ISPN-369, VisitableCommand has been refactored to gain a shouldInvoke() method.  This allows invokers to check whether the command should be invoked before passing the command up the interceptor stack, acquiring and holding locks, etc.

I have updated all command implementations in trunk accordingly, this is just an FYI to anyone who may be considering implementing more commands.

Cheers
Manik
