Allow infinispan client library version to be configurable/updateable

[idlewis]

The script helpers/build/infinispan-client-setup.sh provides a way for users to download the infinispan client libraries into a container image based on the WebSphere Liberty images.
It currently has a hard coded version of the client libraries with no easy way to update/configure the version.
It would be better if the version was simpler to update/configure/override

It looks like the current version used is 10.1.9^*, from December 2023. Current version is 15.x. So, I wonder if any of the inconsistent behaviors we've been experiencing could be related.

(^*Although the build file seems to show only pulling 10.1.3, so I don't know why/how our pods show 10.1.9 jars installed)
