the class FunctionRegistryHolder method addJars.

 * Adds jars to the function registry.
 * If jar with the same name already exists, it and its functions will be removed.
 * Then jar will be added to {@link #jars}
 * and each function will be added using {@link #addFunctions(Map, List)}.
 * Registry version is updated with passed version if all jars were added successfully.
 * This is write operation, so one user at a time can call perform such action,
 * others will wait till first user completes his action.
 *
 * @param newJars jars and list of their function holders, each contains function name, signature and holder
