OSGi version range for Guava imports are too narrow

[guw]

The OSGi version imports for Guava are very narrow. For example, they tightly couple the utils bundle to just one particular Guava release and prevent it from running with latests.

I would recommend setting only a minimum version for Guava but no upper bound.

It could be achieved by adding the following attribute to util_bundle:

    bundle_additional_imports = ["com.google.common.*;version=\"${@}\""],
