[cli.js] Support config.ini

[Rolaman]

Currently, cli.js generates props and store them in config.ini file. The config.ini updates on new smart account creation. We need to implement commands to work with config.ini values.

Project: https://github.com/NilFoundation/nil/tree/main/clijs

• config get: get particular value from config.ini
• config init: init a new config.ini. Add forced option
• config set: set particular value to config.ini
• config show: show the whole content of config.ini file
