PushLocal push local code to the cluster and trigger build there. During copying binary components, path represent base directory path to binary and files contains path of binary During copying local source components, path represent base directory path whereas files is empty During `odo watch`, path represent base directory path whereas files contains list of changed Files Parameters: 

componentName is name of the component to update sources to
