Summary: correct a small defect in openstack_config.set function. Desrciption: When execte command "salt '*' openstack.set file section key true". The function will raise TypeError, because the "_quote" function need a string as input parameter. However, salt bash resolve "true" to Ture a bool variable which is passed into "_quote". Therefore, if user wants to set a string "true" in openstack config file, he must use a command like salt '*' openstack_config.set file section key "'true'". Similar issue also occurs when input a number parameter in salt bash.
