[IMP] move service product to hr_timesheet, move default time unit for services in account_analytic_analysis

By the way, when is this method set_sale_defaults called ?

Moreover, if you have both addons/account_analytic_analysis/res_config.py and addons/sale_stock/res_config.py running, you will have issues. If this method is necessary, you should define a void method in sale.config.settings basic definition, then override it and call super() in both overrides.
