Remove unused jaxb dependencies from pinot repo

[jackjlli]

This PR removes jaxb specifications from Pinot pom files, as jaxb isn't directly used in Pinot codebase.

If there is dependency conflicts on this dependency in the future, i think the better approach is to resolve the conflict at best effort instead of directly specifying more and more versions to Pinot's pom files.
