Infinispan client update

[miuponn]

Fixes#673

Previously hardcoded client version in pom.xml generation is replaced with configurable version at build time or via env in Dockerfile.

Adds support for the following environment variables and build args:

• INFINISPAN_CLIENT_VERSION: Set the base version of the client
• USE_LATEST_COMPATIBLE: If true, script uses latest compatible version using versions:use-latest-releases

@idlewis As you had raised this issue, please review the PR as well. Thank you

[idlewis]

Changes look good to me.
Does this also need to go in 25.0.0.5 (as well as latest)?
Do we also need update our docs?

[leochr]

Thank you for the review, Iain. 25.0.0.6 will be released today (and 25.0.0.5 will be removed from support). Let's target this for 25.0.0.7, in which case, making the changes only to latest would be sufficient.

[leochr]

Please hold off merging as the vNext changes for 25.0.0.6 haven't been merged yet into the main branch. I'll merge when ready.

@miuponn As we discussed, added a couple of comments. Thank you

Consolidated with review comments and issues #704 and #669 and added updated changes to infinispan-client-setup.sh

• Added additional INFINISPAN_DEFAULT_VERSION variable to be referenced instead of putting it in the parameter of INFINISPAN_CLIENT_VERSION for clarity
• Set Infinispan 15.2.6.Final as default client version. 15.2.x is currently under full support until May 2026, supports Jakarta native namespaces, stable and should work with most modern Open Liberty builds
• Infinispan versions 11+ requires reactive streams dependencies for caching in Open Liberty, so the lines that trimmed reactive stream jars for pre-11.0 versions are now a conditional that can be configured if necessary (should not be needed for most part)
• Updated section for removing transaction API jars after installation with new jakarta namespace jakarta.transaction-api*.jar for modern builds

Changes from #744 in helper config files for Infinispan are needed in order for the configurability update here in infinispan-client-setup.sh to work.

Configurability has some known issues for specific client versions and environment compatibility boundaries, will update session caching documentation to accompany script changes
