making cli parse code more ergonomic by remove some copy and unwrap (#347)

Browse Source 
1. remove some unessesary copy in cli parse code of string
2. make some member function into non-member function to avoid taking the self reference.
3. use if let Some(..) instead of if xxx.is_some() to avoid copy and unwrap
