[infinispan-dev] Where to put KeyValueFilterFactory and ConverterFactory...

I was able to look into the details with this a bit.  At first thought
I would think having a module that both the client and server packages
could both depend on would be best.  However the issue is that these
factories produce instances that implement interfaces that live in the
core package, which means the server/client would have to depend on
core anyways.  So I am thinking core is probably the best place for

Thinking about these factories even more it could be useful to use
these at some point in core to allow for non serializable
KeyValueFilter/Converter instances and instead have the factory be
serializable and just create them on each node as needed.

These interfaces provide filter/converter instances to be installed in server/hotrod, but we expect users to provide implementations of such classes and plug the server with them.

With this in mind, core/ might be the best place for it. They cannot live in commons/ cos it’d would require to move KeyValueFilter/Converter and other dependant classes to commons.
